Maybe Lefevers are a bit old for customizing. The typical Lefever you run accross will be a couple decades older than a typical sterly, and many of the Lefevers will sport damascus/twist/laminated barrels. Sterlys have fluid steel barrels.
Probably most custom guns are made for the paticular fancies and desires of the owner, and only a few to fake a higher grade. Right or wrong, the fluid steel barrels will appeal to more owners. It is easier to find spare parts for a sterly which is also appealing.
And the Lefever design is unique and intersting in its own right. Nothing unique about a sterly or trojan.
