The Aust 17pdr production version was the same as/similar to the standard 17pdr built in the UK, with a split trail, low profile, etc.

Can I ask why wouldn't the 17/25pdr Pheasant depress without the counterweight, please?

Thanks

Mike,

Do you have pictures you could post so we can see the differences between the two ?
I have a standard 17 pdr here as well which as you all know were not fitted with barrel counter weights but have the larger heavier cradles which have a different point of balance, they elevate and depress with no problem, the pheasant however has the 17 pdr recouperator inside the lighter 25 pdr cradle and requires extra weight at the muzzle to balance the ordnance better at the trunnions .You can physically depress it without the balance but it takes both hands and a GREAT deal of effort which I have experienced.
Weir's produced 17/25 pdr's were built on standard 25 pdr carriages not altered or lengthened in any way .

All extremely interesting. I am learning a lot!

I only have a print: will scan and post later today. Don't think I've ever seen an image of the Aust 17/25 published anywhere - I just had a scan through the AWM site and only the production version is shown in images from that source.

I wonder if '17/25pdr' that is really 'right' for this Aust weapon? The carriage is of similar design to the all-welded 25pdr, but altered for the 17pdr, so really a different carriage? Maybe it would be more accurately called the '17pdr (Aust) Experimental'?)

To simplify things ,the 17 pdr ordnance and recouperator were standard 17 pdr, the cradle, saddle and carriage were standard 25 pdr (British) the modifications were, increasing the opening in the shield, a bespoke firing linkage and guard and the upgrade of the firing platform by boxing in the angle spokes and reinforcing the outer ring.
One very good question would be ,why does the 17/25 pdr require a firing platform ? when in a direct fire role.............................well I believe that it is as much for ballast than anything else !
