No offense taken.I think that using the Ketland was a great idea, I have yet to see any two French locks that had the same shape cock on them,I was looking to the Grenadier lock on pg 30 of Beauchards book as a sort of guideline, as you said it would not have been hard to get one right from the start,many use the L&R trade lock also, that one and the Davis are to short for my tastes,this itself creates one of the biggest issues with appearance to my eye, but it seems that everything got scaled down on the parts available for this type of gun.I guess it probably does not matter much with a parts set that has a 42" barrel with 1" breech and Maple stock
