The internal search engine on the Brownells web site is junk. If you don't know exactly what you are looking for you may never find what you need. The catalog could also be better organized.
Try a search with the manufacturer field pulled down to HERITAGE GUN BOOKS and the stock number field left blank. The first return from the site should be part number 924-000-001,
THE COLT SINGLE ACTION REVOLVERS A SHOP MANUAL, VOL. I & II. The site does not say that this was written by Kuhnhausen, this may be what is causing the problem.
Price is 34.95.
If Brownells is out of stock, or if you would rather deal direct with the publisher here is a link: Heritage Gun Books
