I recently aquired a very fine Japanese model 90 Double Barrel Flare Gun. I'm not a collector of WWII firearms as most of my collection is all modern long guns & handguns. Any idea on a rough general value of one of these. The blueing is very good for that old of gun, 90 to 95% with only very light slight pitting. I don't have a Blue book that would cover these so any help you can offer would be apprecaited.
Thanks,
