Tony,
Looking good ..... some nice touches going onto your artillery piece. The No.20 Fuze Indicator (ie the slide rule) mounts are 690mm apart, and the top edge of the brackets are 18mm from the top edge of the shield. The right hand bracket is positioned 40mm inwards from the right hand edge of the shield. The two footman loops are 125mm from the top edge of the shield, and the right hand one is 230mm inboard from the right hand edge of the shield. The Loops are standard 55mm centre to centre, 15mm deep loops. The base of the bracket measures 80mm x 43mm, and the depth of the part that holds the Indicator is 20mm deep, 30mm wide. The brackets are held on by 3 rivets, round head type, with the round heads to the outside (front) of the shield. Measurements are from your local gun at Tiaro. I have a good drawing of the No.20 F/Indicator in a Canadian parts book if you want to try and do any replicating, or have it for reference in case something like it comes up for sale. How's the heat and humidity???? We are now basking in 0 degrees again .... mmmm lovely! Best regards Mike

Mike,
Thanks for those measurements. You save me driving to Tiaro again. A piece of aluminium cut to size will do me for now. Good of you to offer though. How bout we combine both temps and divide by two. I'm sure you can live with 15 degrees, and my 15 would suit me fine. I could get back to the engine building without dripping sweat down it's throat. If there is anything you discover you still need measured from Tiaro, just let me know. It is rather closer to me now, than it is to you! I think I'll start referring to my fake as a 'quarter-pounder'. I'm sure you folks in USA will get the hidden meaning.

Well, a couple of things to tell.
20160215_181626-resized-960.jpg 20160215_181755-resized-960.jpg The ranging sticks are finished. The white stuff you see in the retaining brackets is cotton material to avoid scratching the sticks. Have since obtained some thin green felt to use permanently....after painting, of course. 20160217_112035.jpg I have located and purchased a ground anchor cover......in the Netherlands! Purchase price was very reasonable. Shipping cost was horrendous. You only live once. I originally intended not to purchase, but what the hell, eh! DSC_0153.jpg And, the zero plate and block have arrived from Rob N. I'm cleaning the plate right now. The wooden block is a work in progress too. This weekend I want to make the track for the sight door to slide in. Made templates for that, one night through the week. Bought steel plate to make the brackets for the two wooden boxes. Templates for those were made 2 weeks ago.

Rob N, here's your zero block. I tidied it up a little. It will be attached next Sunday.
20160221_200147-resized-960.jpg 20160221_200133-resized-960.jpg Because of a transient episode of laziness, I only spent a couple of hours in the workshop today. It took me nearly all that time to fashion the following piece, being one half of the sight door sliding track. I think it's the harder of the two parts to make, so other one shouldn't be so painfully time consuming. Two hours of hand filing is my limit, I'm afraid. Never again. 20160221_200204-resized-960.jpg It isn't really wider on the right hand side. It's a trick of the angle of photography.

A couple more questions folks.
Sorry for the poor quality of the following photo. 111520.jpg What is the item to left of the rope bundle?? If a shovel, it's not going to be very useful! I occasionally come across photos showing box carrying brackets in locations forward of the shield. Why some do and aome don't? Is it worth recreating this on mine? 075604.jpg And does anyone recognise the type of box behind the soldier. WOW, just WOW! 011315.jpg Impressive photo, but WHY does the flash curve upwards of the barrel angle?!?!?!

Image 1: looks like an an axe. Non-standard stowage, gun crew or Battery mod. A shovel ('Shovel, GS', British p/no JA1320) is the usual (and standard) stowage in that position.
Image 2: again, non standard stowage for a box about the size of the tool box that normally goes on the (true) right side of the trail. Box appears to be an AEME artificer's tool box: he seems to be working on the sighting system. Image 3: camera lens parallax error? Don't really have a clue! Mike

Yes Tony, moderately warmer than a hot air balloon. Combine the gun with the balloon, and you have the worlds largest airbag.
 Wonder if I could use airbag propellant sets in my gun barrel.  I can almost see my nice wooden muzzle brake flying away at great speed. Single use only. I made the second part of my sight door slide last night, and I was correct that it took only a fraction of the time to make. Now to join the two pieces without obvious signs. I have a cunning plan, get someone else to do it. My ground anchor cover is on it's way from NL. If you look on YouTube under "Museum Canadian Allied Forces opent haar deuren op nieuwe locatie" you can see who I bought it from. Mr Heiko Ates. The lucky sod has considerably more toys than I do.

It looks to me as the artificer has just been servicing the layers quadrant, could the box be his tool box? As for the muzzle flash, maybe a ballistics expert can answer that one. Dave.

Could the last photo have captured the moment just after the firing of the gun and just before a facing wind starts to push the propellant gases away?
