Original 16ga M12 in top shape can bring in pretty penny, so I would not modify it. Local shop had one (16ga/28" MOD) with minor wear priced at $700
and it sold. The M12 is best finished gun in slide action category. Unlike ole 37s they're not sleepers pricewise nor as portable as LWT 31s, but certainly best finished and best lookin in trombone category.
PS. 16ga.com might be good place to move that 16, but don't expect to get top price, because most of those penny pinchers think candy bar is still 5 cents!
