I had Apple Hydraulics re-sleeve the original master cylinder on my '74 R90s and it came out great.
With 150k, my last rebuild (new piston and seal) was still allowing a drip or two of brake fluid in the rubber catch boot, so I took advantage of their re-sleeving service.
Got it back, bench bleeded the M/C, hooked up the lines and finished the final bleed. Took all of 20 min.

Good people. I'm just a customer.
