IRA Green and Hilborn & Hamburger Hallmarks on Para Wings

[triplecanopy]

Here are three hallmarks that I have had a while and cannot identify the maker. The first is marked H24N. There are no other marks and it is a clutch back parachute badge. It is die stamped.

Second unknown is this basic parachute badge simply marked 3G. It also has the initials "MK" scratched on the back and this badge is well worn and has the suspension lines polished away. It has been bent so that the canopy is convex or pushed out slightly. It appears to be sterling, but not tested. It is die struck. Any clue who the maker was?

This is another unknown I have had for years. I can't recall when I got it either. It is deeply marked J.J.W. It has a British style pin with a "C" clasp. I don't think this one is stamped. It may be cast. It has a single combat jump star on the left wing as the viewer see it. Maybe a copy or phony wing for collectors. Anyone see this mark before?

Here are all three together. This angle may be a bit clearer.

After a bit of searching, I found that 3G is an old hallmark for IRA Green. That company was started in 1943 and is still in business. Evidently 3G was an early hallmark that I had overlooked.

I do believe that the H24N is a hallmark used by Hilborn & Hamburger. Another one solved. Thanks.
