mystery guns

[Les Freathy]

I thought i would start a thread dedicated to gun mysterys that need identification. I for one have a few bits that still remain open in my folders including these two photos of guns built in WW2 by the Baker Perkins company at the Westwood works. The first photo states a 2pdr gun, well its the strangest 2 pdr i have ever seen the second is a twin barrel A.A gun on a four wheel carriage

OK gunners its your call
cheers
