I didn't coin the term "Never a screw turned" when referring to a gun in pristine condition with mint condition screw heads. But I'd bet that whoever coined the term wasn't an anal nit-picker who thought that meant that the gun was originally assembled at the factory without turning screws.
As another sidebar...
Funny that you mention the Lefever Optimus that was supposedly restocked by Keith Kearcher "not too long ago". He's been retired since around 2009. His business was taken over by his nephew, and there have been a number of complaints about his nephew's work right here on this BBS. Many considered Keith Kearcher a master gunsmith, and he was one of a very few gunsmith's who were always highly recommended on the old Lefever forum. He never did any work for me, but I know he was able to substantially disassemble my D.M. Lefever crossbolt without any sign of it being worked on. But maybe tarnishing his star will make yours shine a bit brighter. You may remember the so-called "Clunker Optimus" that was restored by him in 2008. The gun was in horrible condition when purchased, with metal straps screwed onto the shattered wrist which had pieces of wood missing.
The intent of this partial restoration was not to make the gun look like new, but to do a conservative partial restoration to save a rusty pitted total basket case Optimus from the scrap heap. It sure doesn't look like Dremel Tool work to me or people who examined it at the Las Vegas Antique Arms Show. I wish I had a "Before" photo. It was so bad, a lot of Lefever experts initially thought the buyer was nuts to spend $6900 (including buyers premium) on this Optimus.
