Wonderful restoration Brian, and thank you for the advice you have given me over the years in my own restorations! When I restored the M1860 Dragoner, it had many cracked stitch lines on the visors, and a couple of small missing pieces. I used superglue and new thick leather to do the repairs and then re-drilled the holes. The superglue capillaries through the leather fibres for a very strong connection. The thick leather on the M1860 made this technique very effective, maybe not so good on a fine leather Private Purchase helmet?
