Yup the serial number is in the 250 range. The gun was assembeled from stock for a skeet shooter named Green. I don't remember his first name but his 4bbl set is mentioned in TPS and the gun was purchased from his family on the Eastern shore of MD. It's a two bbl set, the Parker bbls are 26 inches IC/M and the second set is from James Purdy and are 28 inches M/F.
The watertable has lightening cuts, it's a OO frame and it's marked grade 8. The barrell flats are stamped A1 but who knows. All I know is it's a nice gun and I like it and I shoot it pretty well....so far
Maybe it's a canidate for the last Parker built.
