rj,your gonna have to pay plenty for an original catalog,but Audley(and Folsom)were listed in Stoegers "Bibles" in the 30s-50s;sort of a reproduction/condensed version. I think the 1940 edition has been "reprinted" and a helluva lot cheaper than paying "collector" prices. I will try & check my "library" for a Stoegers tomorrow. I have an Audley,and love that "spring clip".It WAS a police holster,with a swivel & a 6 cartridge loop,in black for a Sam Brown Outfit. Came with a poorly reblued over light pitting Army Special in .41 Colt,with 5"bbl,but a great shooter(& lighter than .38s & hard hitting with handloads.) Anyway, holster bottom pretty worn,so Ive "converted it" to handle my 4" Marshall or 4" .357 Model. Bud
