Infos on early Ithaca 1911A1

[Mikecp@2022]

Thanks for your reply, that's what I thought too.
For my knowledge on M1911A1 I have the book of Mr. Joe Poyer " The Model 1911 and model 1911A1 Military and commercial Pistols" a book of 522 page, as well as the collector's Guide wrote by Charles W. Clawson a book of 146 pages. I'd like to find even used one the largest book of Mr clawson "Colt .45 Service Pistols, Models of 1911 and 1911A1 By Charles W. Clawson copyright 1991. But the prize is prohibitive on eBay around 700.00 bucks. Is there another way to get this book with a more reasonable prize?
Thanks for help.
