Collectors: 2 Book Set Winchester & Colt Engraving

I have a 2 book set, hard covers in a leatherette container, of Colt Engraving and Winchester Engraving.
the books are like new but show wear on the dust covers...most places that are offering this set are selling the set for $500.
I am selling the set of books for $275.00 plus $20.00 shipping and handling...these books are the definitive book of Colt and Winchester engraving and are loaded with beautiful pictures. The books are around 400 pages.

 

are there any model 50 winchesters pictured in the winchester book?
