Lyman's trad MLs had been built by Investarms and were Very good machines indeed. You could actually work on them, take them totally apart - their breech plug IS removable! - and are good workhorse rifles at their basic introductory price tags. I've had a gaggle of them and all were very good rifles. Some would opt for a better lock, and I did with an L&R more than a few times, but even that was not at all mandatory. The fact that the Investarms lock could be fully disassembled and "tuned" was another solid reason to buy a Lyman trad ML ... or an Investarms trad ML from DGW - they are/were one in the same, with typically a lower price tag for the DGW offering.
I've also had more than a few of the older (perhaps by 10 years) Pedersoli trad MLs and (unlike their Pedersoli BPCR guns), I wasn't impressed with them. The bigger issue was the near welded breech plugs. For all intents and purposes, they were welded because I could never get the buggers off, and I have proper gunsmith breech removal tools. I never found their locks any better than the Investarms locks, either.
It will be interesting to see just what a doubled or so Lyman price tag will get you with these Pedersoli guns.
A DGW flint .50 Investarms kit ("kit" is almost a joke - these are all easy "screwdriver build" guns) with double set triggers is now $525 when it used to be $425. The same rifle completed is now $595. Times have changed, er, inflated. Grrr.
