Ross, your triggerplate gun is neat. I have only seen three of this model New Baker with Damascus barrels and engraving. The serial no. is out of sequence, though. It is in the Model 1897 range. I think the 1888 or so flyer on the New Baker [two of which are erroneously dated in the 1870s by Abby Books] shows an engraved triggerplate gun. Yours has more engraving [etching] than the others. Seen the DGJ article for dates on hammer guns.
