Mystery Inglis HP with aluminum frame

[Nagato2ca]

Hi All,

I finally received an Inglis HP I purchased last August. When I opened it up today I was a little annoyed as my first impression was that it was a lunchbox gun. It had no visible serial numbers and the finish on the frame and slide were different. Upon closer examination I was very surprised to find almost no markings and further shocked when I disassembled it. The frame weights almost nothing, its featherlight. It has to be aluminum or some other very light alloy. The only numerical markings are a 7 behind the magazine well and the roman numeral II in two locations on parts of the frame. The is a faint marking on the breech of the barrel and below and left of the ejection port on the slide.

Given the extreme rarity of the experimental Inglis lightweight frames I can only assume this is a later component that someone happened to put an Inglis barrel and slide onto. However, the very few markings and the location of the 7 stamp behind the mag leave me questioning what the origin of the frame might have been. I have also compared it to the later FN made aluminum and the locking shoulder pins design doesn't match. They have a round pin while this on had a pin that is squared off at the top and front. I'd appreciate any help figuring out what exactly I have here.
