My thanks to Robbie for his reply concerning Wurlitzer "R" rolls
[200502 MMDigest].  In fact, my partner had created rectangular labels
using the circular labels as a basis.  Comparing these new creations
with the sample images sent by Robbie has shown that they are virtually
identical!

I have now found first names for a couple of the organists.  It seems
almost certain that there were two "Gibsons".  There is a James Gibson
AND an Archer Gibson.

Does anyone have a list of their "RJ" rolls?  Most of the organists
were common to both systems.

Thanks again,

Richard Cole
