I can take some photos of the inletting tomorrow. I wanted it mostly for the rear sight and the buttplate. I was surprised when I found the HOWE stamped in the barrel channel. I don't really see anything that looks James V Howe to me, does anyone see anything?
I'm also puzzled by the caliber marking, does it look like maybe the way Newton marked his 30-06?
I don't think the barrel is GI as it doesn't have the pin slot on the bottom and the rifling looks a bit different.
The serial number falls in the Mark I range so it was probably a 1920 NM action.
