That's not Winchester custom shop engraving.....aftermarket engraving and Pachmayr would have added sideplates for more engraving surface as they did on many 21's and Parkers, so I doubt it's work done at the old California Pachmayr custom shop. I saw these on an internet site earlier; extensive engraving and deluxe style checkering; a Winchester custom shop gun would have most likely had A or B carved checkering with John Durkin's signature fleur de lis carving. Winchester records from Cody are circumspect at best.....Pauline Muerrle could tell instantly if this engraving was done by anyone that worked in the Winchester custom shop. As far as even remotely resembling a high end Turkish gun, that just shows the extreme ignorance and lack of knowledge exhibited in that comment.
