I contacted MVTC and Pete answered my email. Here is his response about the Bakers you all might be interested in.
"The Bakers don’t have a set trigger, but they do have a yager-style trigger where it lays backwards at about a 45 degree angle. They have a standard two-notch tumbler with no fly, so if you wanted to slick one up, it would be an easy job.
As they come, they have smoothbore barrels, but Colerain makes a .62 cal rifled barrel for the Bakers that can be fitted. We get them (the rifled barrels) from Track of the Wolf and the gun can be ordered with the upgraded barrel. We fabricate a breechplug out of 4130 round stock, reuse the original sights and bayonet bar, then brown the new barrel and breech assembly. The gun with Colerain barrel sells for $695 plus shipping, but it is still the cheapest way to get an actual rifled Baker as opposed to the smoothbore.
Thanks,
Pete"
I'm going this route I think. The Colerain barrels have a 1 and 66 twist and are 30 inches long. The barreel won't be a Rayl, but Colerains are good barrels.
