Ezra, i just started working on my rifle Shoppe M1743 Marine musket.Some what similar to the 1728.I got a nice piece of euro. walnut that I cannot complain about at all.the assembled lock was well put together and really will not need tuned at all.[i cant say that for the davis french locks i use a lot of.]The iron castings were all about on par with others i have used.the Colerain barrel is fine.the cast bayonet,which you can see thee original armorers marks in the casting was a little rough[think lots of filing, & sandingthe stock profiling was rough to say the least,Not anything like Dave Keck's work.The barrel inlet was rough also,the breech area needed cleaned up & squared just to get the barrel seated.The forestock had already started to bow some.
I did a St. Etienne FDC for some one a year or so ago using TRS parts and the woodwork was better.now on that gun we had other issues.
The pre drilled lock bolts were dead center in the RR channel & the lock inlet was a tad large in a spot or two.it ended up being a nice fusil.
on this m1743 i asked them not to drill& tap the bolts or inlet the sideplate.The Trigger guard & buttplate were inlet also.On the SE gun we had not problems with that.
While IMO its not the most challenging of builds,it will make a unique gun that is to original dimensions.now that i have a pattern or model,If i do this gun again i would order the parts from them & have Dave Keck do the other work as needed or desired.
I put another project aside to do the 1743 so i'm a little enthused about it.Plus all the parts from TRS in a month
I hope this helps some.
