Antique Clocks/What does the R &A stand for in my Westminster chime movement with R & A pendulum,

I would subscribe to the "Retarder and Accelarater" (or "Accelerer") version as it explains the mark of equation (=) between R and A, i.e. R = A as it appears on our wall clock.

Mel Hombre is way off course.  The R and A on the pendulum have nothing to do with clock makers.  If the letters were in English they would be S and F,  meaning Slow and Fast.  The nub at the bottom of the pendulum is the adjustment when the clock is not keeping accurate time.  In lieu of the English letters, however, many have the French equivalents of "R" and "A", meaning "Retard", or slow down if the clock is running fast, and "Avance" meaning speed up, if the clock is running slow.

R&A (R/A) = Reverse Advance, a 1900's term, however the term is no longer used.
