That's a great looking "rig" (if bayonets are "rigs").
I used to collect bayonets, had a few really desireable ones, several really early, which is not my normal area of interest.. I had a nearly mint 1937 dated S/239 code, that's a tough catch. (Uncle has it now - I'll get it back someday!) I do want to get back to it, but I want to try to rebuild my decimated rifle collection.
Much like the binos I also collect now, you can get a really nice piece from time to time without breaking the bank, unlike rifles (at least for me, my "bank" is small). I need to find a rivet grip and a phosphate sgx, first off. All I have left is a beat up early EP&S as an example, and a WKC dress bayonet with frog I have had since I was a kid (anyone have an extra felt ricasso pad?)
I love your bayo, and the frog is exceptional. Man, you take great pics, Mike.
