TR2/3/3A Girling Brake/Clutch Master Cylinder [slant port] Variations?

My preference is to reuse the old master cylinders for my '59 TR3A and send them to Apple Hydraulics for sleeving. In taking a closer look, they are not identical castings. One is stamped "Girling 75" and the other simply "Girling" in smaller letters. Both have (as best as I can make out) the numbers "310680", although the latter appears to have "·02" added at the end.

Does anyone know if this is simply a case of the original being replaced somewhat later with a slightly changed Girling replacement, and which one would be closer to the original Standard-Triumph installed version?

Has anyone had experience with the Moss Classic Gold reproductions? I believe there was discussion several years back of some problems with those?

Appreciate any info.

Regards,

Walter

It was my understanding that the originals would have vertical ports (not the slanted) though I have no personal knowledge of that.

As for Moss Classic Gold -- aren't Girlings still available?

Hello Geo,

To my knowledge, only the TR3/early TR3A had the vertical ports. Apparently TRW/AP Hill are producing a very similar if not identical version. Thanks!

Hello Art,

Thank you very much for this information. Odd that the other suppliers list some TRW (Girling) models, but not the one for the TR3A. Appreciate it!

Regards,

Walter
