parker barrel with no serial number

[Steiner]

Those barrels appear to have been built with ejectors. There is no retaining screw and the dolls head looks like an ejector type. That would explain the welding of the parts. I have a "FrankenParker" that is similarly altered. Also looks like the barrel lug may have been filed at some point, explaining the lack of serial number. A picture of the left side of the barrel lug and a clear picture of the underside of the dolls head would help.

Really not sure what to say.. There is no excessive wear or filing anywhere.
The bores are as nice and shiny as if they were freshly honed. Possible, but there doesn't appear to be any thinning.
Someone likely cleaned up the Damascus pattern and put a lacquer coating on it, or so it appears.
Thank you, BigJim
