Tom, here's one I'm doing for my early Francotte varminter. I made the barrel on the end too small IMO but that's personal taste. I've inletted the grip cap and PG so the back of the lever will nestle closer to the grip but it still looks awkward to me. This IMO is the area where most Cadet smiths fail in forming an attractive final product. The curve of the wood at the grip combined with the curve of the steel lever and the difficulty of fitting everything properly has proven to be my biggest stumbling block with these splendid little actions.
Concerning the difficulty of low-mounting a scope, I've discovered that the comparatively higher line of the top of the wrist/grip (compared to other single shots) actually helps me with mounting the scope low enough or rather positioning my face high enough for me to use it comfortably. I make the buttstock's comb nose fall just below the bore line giving just barely enough clearance for the cleaning rod to enter from the rear. This automatically positions my face at the proper height for a low-mounted target scope and gives plenty of clearance for loading/unloading. Here's a full view of the same Francotte varminter.
With a normal modern 1"-tube scope with enlarged eyepiece, however, the scope must indeed be mounted somewhat higher than minimum in order to give more clearance for loading/unloading. Much depends upon the size of the cartridge case, the scope's eye relief and the shooter's manual dexterity. Here's a comparison of the Francotte varminter with an ELW Greener takedown fitted with small 6X Burris. The Francotte is 219 Improved (30-30 case) while the Greener is 224 Maxi (357 Maximum case); both setups have enough clearance for loading/unloading and both scopes are positioned for my eyes. I hafta add that the little 6X Burris has a truly impressive 4"+ eye relief and this is one reason I chose to use it on the little ELW Greener. Another scope would almost certainly have to be positioned further to the rear or higher. I also hafta add that the Greener's hidden right sidewall has been lowered very slightly (~3/32") for better loading/unloading access.
