Angel,
If you had been around between 1920 and 1922 you could have bought this same Parker at Von Lengerke & Detmold (#173979) as a used gun for $275. It was sold three times during that period. The sale recorded in the photo below shows that it was sold as a consigned shotgun in 1921. It came in from J.A. Sloan who wanted to net $225 from the sale. The parker was sold to Gus Diderrich who was a chef for Alice Vanderbilt and, later, for Peter A.B. Widener, a very wealthy Philadelphian. Gus Didderich was one of the most frequent buyers of very high end firearms (Purdey, Boss, H&H, Parker, etc) between 1910 and 1930. He must have been a darn good cook. But to keep things in perspective, $275 would likely have bought you a new Ford at that time.
