Although the ad/catalog copy has been posted previously, I've neglected adding the early Guardian fit codes to the list. I updated the pdf in the first page of the thread to this 2024 version.
Showing Federal Man also so all can work out the transitions from Guardian numbers to Federal Man!! [Colt DS #920 became #200. 940 became 400. 944 became 440. But it's not a firm rule.]
