CC Johnson is of course renowned here for his single shot work but a couple weekends ago at a Harrisburg PA gun show I found a Savage 99, ser. no. 141474, barreled by him in .219 Zipper.  Barrel a bit heavier than a standard 70 pre64, 24".  Mint bore.   Stamped .219 Zipper top line C.C. Johnson bottom line.  No Thackery Ohio stamp.  So according to CCJ's grandson Jerry C. Johnson who occasionally posts here that means the barrel was put on after CCJ moved from Thackery to Lawrenceville OH in 1947.  This is confirmed by the barrel number underneath, 51026 BMR, according to JCJ the first two numbers are the year, which would be 1951.   Is it the 26th barrel CCJ fitted in 1951?   And what does the BMR stand for?   Perhaps if JCJ sees this he will explain.   As apparently is often the case the woodwork is unexceptional, the stocks are in the Fajen Aristocrat style if some of you gents remember it, flat bottom scoop sided forend, hook pistol grip, slab cheekpiece, plain wood, no checkering.   Workmanlike and OK for varmint work but, frankly, ugly.   It has Weaver bases, no iron sights or slots.  I have some old factory ammo and will try it out in the next few weeks.   

Sounds like it was built for somebody that had figured the woodchucks had taken over his farm, and he was out for some pay back.

51026 was the 26th gunsmithing job of 1951 - all work received a job card, whether rebluing, repair, drill and tap for scope mount, or rebarrelling.
Prior to Diller's death, CCJ preferrred Diller barrels and liners (Diller made .22 rimfire and .22 centerfire barrel blanks and liners) , but would install what the customer supplied or requested.  After Diller died, his personal preference was Douglas for barrel blanks and Parker-Hale for liners.  I heard many tales of barrel lining and blank contouring  from mu dad, who helped in the gunsmithing shop while growing up. 
As to codes:
BMR is Buhmiller, Doug is Douglas, Doug XX is Douglas Premium, still trying to decipher others.   
Can't find the card for 51026.  Best guess is that the customer bought a semi-inletted stock and fitted it himself.  CCJ did little stock work, never building stocks from scratch.  he was always far too busy with metalwork.
