My HS is also a 1947 H-D Military. It's condition is very rough and needs a complete rebuling. I had a local gunsmith take a look because it was inoperatible. He MADE two (2) springs and did some cleaning then fired it several times. I am not satisfied he understood the HS but I have not fired it myself.
The gun was given to me but it appears that it has a long row ahead to bring the gun back to condition. This is my first exposure to the HS and I believe I would like to keep. Maybe I could give the gun to anyone for parts and wait for the opportunity to buy a well conditioned HS.
