MarkOue, the price for recaseharden Frame and Parts was $18.00 for Field Grade and for the Monogram was $30.00. The price difference was in increments of a few dollars to the $30.00.
Blue Locks and receiver was #12.50 for all grades.
In "The Legend Lives" there is only one parts list for 1941 and doesn't list "Blue Locks and Parts, only lists "Blue Trigger Guard and parts".
This is almost like a few that have written saying their receiver and sideplates are nickeled or chrome plated, and I believe that one person actually had proof that the gun was sent to Ithaca from Fulton for said work.
To me this is what makes it very interesting in these guns, written in a book doesn't always make it so. I guess Burger King might have gotten their slogan from Hunter Arms, "Have it Your Way", also "anything within reason"
