[Austin W Hogan]

The engraving on the frame and locks, plus the checking pattern indicate that this is probably a grade two. The barrels' damascus pattern does not show in the photos; this might just be due to the flash, or may indicate the barrels were blued at some time. The gunsmith should examine the barrels for any problems that might have been caused by hot bluing. There is a list of gunsmiths and restorers elsewhere on the forum.
Nice looking gun, from a nice era in Parker Production.
Best, Austin
