I'll second Jim Downing's work - especially if you find him a copy of the styly you'd like.
He's fairly fast - for what he does - and you'll no doubt be pleased with the result.
Henrys are great to doll up, and engravers love them - all that soft brass and those flats make their job both easier and faster, since they can set to work as soon as they place the transfer onto the surface.
As an aside - when I started collecting - a helluva long time ago - Henrys and Winchesters literally abounded - as did Colts and the rest of the run of firearms used on the Frontier.
Most of the Henry rifles were engraved - but engraved long after the fact, as an 'enhancement' to the prospective buyer.
Back then - none of the reference books were available, as they are now - and gun dealers' reputations were on a par with those of used car salesmen - unless you 'knew' someone.
Everyone else was fair game.
As a young collector - I was told several times over the years that the dealer who had an un-engraved Henry mostly had one in original condition, and to take a closer look at it.
Vaya,
Scouts Out!
