The information in both hard-copy and internet reference sites is almost exclusively base on what can be seen. In this case, an easy mistake to make but still incorrect. Also, the Bren Tens were Standard Models with hard chrome slides but fitted with internally modified .45 ACP barrels. There were two, both with special serial numbers. The second belongs to Don Johnson although it was on display (and incorrectly labeled) at the Las Vegas Planet Hollywood for a very long time. To my knowledge, it has been gone from that site for some time.
