Just as follow up, they are now available (and have been for a few weeks) and several posted on gunbroker. I am unsure how many were made but some sellers have quantity in excess of 10 on GB. They seem to be selling in the low $700's which was shocking for me but I snatched one up so the .44 Mag SBHH Bisley will get a break this year. I only have two weeks before gun season starts so I hope the HSM Bear Load +P 325 grain loads shoot well. No time for load development
