I picked these up from a seller who, in turn, got them at a garage sale in northwest Washington, not far from the town of Mt. Vernon. So, it would be logical to attribute them to that location. Trying to get better evidence I was in Mt. Vernon yesterday, talked to people at a sporting goods store, gun shop and perused city directories at the local library with no success.

Here's my question--what kind of evidence should I have (assuming more is needed) to attribute these to that location? I'm still exploring other options but becoming dubious of finding more.

Does anyone have the records for this mold?

Thanks--no traders at this point.
