It "looks" (there are pics) like the MkI (or I*) 3" 20cwt and recoil system was mounted on a redesigned but quite simple pedestal mount inside the Gun Carrier's "armour box"...with a little round mantlet mounted on the gun so that it just overlapped the edges of the hole in the box's armoured front face! Not a lot of time (equals money, after all!) seems to have been spent designing the new mount...Very true but that was the whole gun and recoil system not a cut down gun and a new mounting and recoil system.
Are you talking about the photos of the gun carrier pulled off the ranges recently, where you can see inside the fighting compartment? They do show the same recoil system as on the AA gun. I also recall seeing some pages of the manual showing the interior stowage which show the same mounting.

At least Pemberton seems to think they were a bit more substantial than "Nessie"!
Probably they were all re-barreled with the correct weapon as soon as production caught up - and there's always the chance that those intended for the ME were sunk en-route....
Pemberton does not give any more information than Hogg, it is possible that is where Hogg got his information from. For the guns to have been accepted in service there would have had to be some form of handbook, they done one for the 50 SP guns. There would have had to be something like a range table. New sights those from the AA gun would not have fitted the 17 pdr carriage. A anti-tank gun is no good without sights. 50 gun tractors with a different stowage arrangement would have not gone past the vehicle enthusiasts noses without comment.
What does seem strange that in the Pemberton report the carriages were well in advance of the guns in April 1941? The 17 pdr was not approved of until May 1942 and to get it into action as soon as possible where the guns that were advance of the carriage production the guns were mounted on 25 pdr carriages. So the carriage building programme must have been slowed down from April 1941, before the approval and September 1942 when the first 17/25 pdr was test fired.
It still beats me that 50 guns were made and no official photo or an unofficial one. How many twin 6 pdr anti aircraft guns were made? How many photos of the two of them? The British liked to photograph their development weapons, photos the 17pdr Straussler Monitor is well published and so is the Thornycroft Amazon 17 pdr SP. So why not the 3 inch gun on the 17 pdr carriage after all neither parts the gun or the carriage were top secret.
Which units did they go to, or did they remain in storage like the 95mm Infantry Howitzer?
As for them being re-barrelled with a 17 pdr gun I am sure that would have been documented. If they would have been lost at sea they would appear on the Lloyds register as cargo losses.
