Hi Jeff,
Thanks for the information.I have just started researching this Kerr and assumed 9522 was the patent # since it is stamped Kerr's Patent 9522 but thanks for the correct information. I will get some pics to you of the holster. I have tried to get the Pratt List on the web with no success. Could you give me the listing or tell me how to find it? Many Thanks. Brander
