Hello Lyman,

88,320 shipped 10/2/1941 to Sloss & Brittain.

Failure to eject or failure to extract? The chamber might look clean but have baked on oil that needs to be scrubbed out. Best approach is a solvent soaked bore brush that you spin slowly in the bore using a hand held drill.

Other causes for bad extraction can be a dry fire dimple in the breech face.

A old or damaged driving spring could also be a contributing factor to your problem.

The source of parts is limited. Numrich offers old used parts and some almost right misc parts.

Brownells, Jack First, and Wisners are other potential sources.
