I can recommend Clarence Gass to you.

Tel: 913-432-6057
Clarence is willing to tackle anything, very reasonable in his rates, and gives great results. You can telephone Tues - Friday 9-4PM Central time.
Clarence sets his focus using ground glass on the film rails, a magnifier, and a tower several miles away on the Kansas plains.
He's corrected focus on cameras that other techs have not been able to get right using autocollimators.
He fixed the focus on a Zeiss Super Ikonta C that a well known West coast Zeiss only expert was having trouble getting focus right with. I also referred another fellow RFFer to him. The RFF-pal was having poor focus on his Rolleiflex T, after overhaul by a well known East coast Rolleiflex expert. Both cameras have Zeiss Tessars of about the same era, when Zeiss was supposed to have incorportated Lanthanum elements into their Tessars to improve color rendition.
Anyway, here are some test shots that I made with my Aires IIIL 35mm camera, after Clarence overhauled it. This camera is a fixed lens rangefinder from the 1950s. It can focus down to 20 inches. Here it is at 20 inches.

Thanks for the info! So would I be sending both the camera I intend to use and the lens that needs calibrating?

Send both the camera and the lens
Send both the camera and the lens
To send both camera and lens together is the best way. The lens could be off, or the camera rangefinder could be off. If you send both, then he can make sure that both are properly adjusted - not just for each other, but for other properly adjusted cameras/lenses.
I had this done for a Canon 7s with Canon 50mm 1.4 lens in LTM.
All of my focus tests are done wide open at minimum focus.
Here's the Canon equipment after it came back from Clarence.
Focus is on the card with the cross and the "0" marked on it.
