This older post seemingly caught your imagination The topic has come up very recently ,like yesterday ! It is possible to make & post 'Stage props' but the barrel needs be fitted in the US or where ever you are . locks I make. I don't think TRS have such specific locks while early ones tend to be Snaphance but many had varient 'English' locks even pure 'dog' locks that are just a full cock & the 'Dog' served quite happily as a half ( Where are you anyway ?) .Post is expensive & I' charge like a wounded Buffalo '! Well not by many standards . I've made and used all the varients even pure internal flint lock it all depends on the patron tastes. I once put into Dixons fair juror's a Snaphance Lemon butt pistol .because it was all l had with me . now these Jurers know ALL about US pistols but 17 Scots don't come up often they pointed out the thissle muzzle" Shouldn't have ' Knurling '' It didn't have any just my hand files .Took a prize anyway . While Ile consider your desire .PM me and see how we go. Rudyard
