Hi Rob,
I know he was 372nd Battery, 114th LAA regiment RA - would the service records give us any other information or just confirm this? He does talk about it, although he is a bit vague about some things, and maybe requesting the records might help him remember a bit better. Thanks Rob! Rachel

However, I am looking for pictures of the 'Carrier Predictor AA no 3 SPM', also known as Morris-Commercial C8/P SP Predictor. Who can help? Thanks, Hanno

Just seen this thread, interesting! have a book about Firestone company history, and it tells all about the development and building of the US made Bofors guns, interesting! will see if I can find it.
Any idea what this on the picture is? all Airborne equipment, but looks bigger then 40mm ?? Cheers, Lex

Welbike,
The photo shows a Mark 4 platform's outriggers. It was a modified Mk2 or Mk3 platform which had the fore and aft girders complete with their axles chopped off, and fitted with tubular extensions so that they could be reconnected to the central part in the same way that the side outriggers were. In this way the Bofors could be split into 2 loads, one comprising the Ordnance, the mounting and the central part of the platform, and the other is the stuff in the photo. Cheers

Hello Mariano,
I am a volunteer at an aircraft museum in England (http://www.shuttleworth.org/) ... we have a 1938 Bofors gun amongst the exhibits. On airshow days we set it up so that visitors can operate it and try and track aircraft. During this winter we have to start some maintenance and also try to reset the sights, which seem to be aimed badly. We are also interested in the corrector that you dismantled, and want to find out more about how it operates. Would you be willing to share your knowledge and experiences with us ? For example, how do you remove the sights ? Many thanks Richard

Hello Tony,
I know its a long time since you posted the diagram of the sight corrector... bt can I ask where that diagram came from ? Also, do you know of any disagrams that show the gearing in the axle assemblies that let the wheels 'kneel' and in the bar carrying the sights ? Thanks Richard

I would like to take a moment to introduce myself and tell you why I'm here....
I am a volunteer with The Shuttleworth Collection (in effect, an aircraft museum, but I should not really call it a museum. Just about all the aircraft are regularly flown and the vehciles we have are regualrly driven and displayed). The collection has a Bofors 40mm AA gun, which we display on flying days and invite the public to sit on and operate (which is a lot of fun if the aircraft are flying at the time). We need to learn more about this gun, and do some maintenance on it during the winter. This is the gun in it's weekday static display position in one of the hangars....

There are a few things we are having trouble with. Firstly, this is the barrel elevation mechanism.
We have a slight oil leak from the bottom of the vertical column. We are not sure if this mecahism is supposed to run in an oil bath or actually be full of grease. It's possible that over time some of the grease has liquified, or that someone put oil in it and then topped off with grease. If anyone has some information about how this is supposed to be lubricated I'll be very happy to receive it.

The next problem is the 'accumulator' springs. These are in the two horizontal tubes under the barrel and contain springs that compensate for the weight of the barrel. In our gun the springs seem to be very weak and let the barrel fall under its own weight. We assume that the springs need to be removes and re-tempered. Has anyone done that or know anything about it ?

Then there's the sighting corrector. We've worked out what most of the dials do (though we're puzzled as to why it turns around as the gun itself turns). However, we're not sure of the purpose of the white metal horizontal dial that is situated at the bottom. It has markings of 0 to 40 (which somewhat mirrors the vertical azimuth scale that's in front of the operator and goes from 0 to 400). Any ideas anyone ?

Nor have we worked out what these two controls are. Each knob can turn three times, each has two opposing scales. It feels as if it's some sort of coarse setting for the sights, but we have not been able to set them in such a way that the sights exactly match the barrel.
Just for completeness, this is a closeup of the actual sights. We know that the items that look like boxes are the night sights. As I said earlier, any information will be gratefully received ! Many thanks in anticipation !!

Richard I have found my copy of a small Finnish manual I have and it is listing that lower dial as a "pysyttimen 7". Google translate is not finding this word so hopefully someone will chime in and translate. I believe the two upper knobs are for zeroing the sights and may not line up exactly with the barrel due to minimum range and bullet drop ??
If you can post your email I will scan in all relevant pages in my manual and send them to you in a zipped file.

Scans sent - if you need any other details please let me know. Still looking for one more reference book (no luck yet) so I will email you if it ever shows up !

I do not have much information to contribute to you, since it is blindly reassembled without having an exploded manual, nor do we know if it is well adjusted. As we only have it as a display, we have not studied the subject of the sight in depth. If you need other photographs, I will gladly send them. Best regards Apologies for my English, it's not my native language.

We will keep investigating how our Bofors works and if we find something interesting I will post the information here. Notenoughtoys has kindly sent me some scans of a manual (unfortunately in the Finnish language) but one page does show an exploded view of the corrector (also called the calculator) and I am seeing what I can deduce from that. Very best wishes Richard Best regards Richard

I plan to visit one of the museums in London soon to see what manuals they have in the archives for the Bofors gun, so I'll hold off asking for further help on this forum for a while. Thanks again! Richard

Also... as far as I can tell, your gun has the same sights are ours. These were made by a company called AGA-Baltic. See.... http://www.aga-museum.nl/page/reflexsikte
