1) Here is an unused, as far as I can determine, carved Heiser 721 for a 7" S&W M41. There are similar ones listed on auction sites for well over $400. I'm asking $325, shipped. (Or, will trade for a similar value, high quality holster for an M41 with a 5" field bbl, not 5.5 HB.)
Gun not included. More pix and info on this holster here:

2) Heiser 225 is SOLD.
3) Heiser 434 flapper. $75 shipped. Fits a
fixed sighted k-frame. K-frame target sight will not fit. (My 4 inch M65 slips right in with length to spare, so I think 6" length. Was told it would fit a Colt Official Police, but don't have one to try.)
As shown, somebody punched in their name on the edge of the flap at some point. Also, belt loop leather looks a bit fragile with age. Holster probably better for display piece than as a user.
