Hiding serial numbers for above reasons, and they aren't my guns. Yes, i agree now they are west hurley guns. The hive mind helps you think of all things. The back half of the receiver has the typical "M1" marking. The front doesnt have the semi auto step so these were never converted from a 1927.
A new member here asked me to look at his guns and help him post pictures. I believe he said they are form 3 (last transfer to him). They have 3 digit serial numbers with the pictured letters behind them. Anybody seen this before. They may have been movie industry guns. Input would be welcome.
We've had the chance now to watch a couple stock parts sell. A vertical grip sold before this for $2000. Now this. As if this writing a rear grip has a $700 buy it now thst hasnt been grabbed.
West hurley frequently have deep bolt pockets which means if you put the gun in semi auto, the rocker rises up and the bolt can travel over it which can then cause what you describe. Confirm if this is happening when you have the gun in semi
Kahr and west hurley thompson receivers all have the same acme threads. But some receivers are a bit tight and poorly done. My advice is if you can't screw a barrel in by hand, don't force it. The threads on the barrel may need dressing a little bit in all directions to ease assembly. Major and minor.. and sometimes even the width.
Remaining threads in barrel look good for what I described above. There isn't the pressure in this barrel like in a bolt action Hi power rifle. You will be fine.
