Identified through online information from Eric Schmiedeberg. -- Updated by Eric Schmiedeberg <br> <br>For a specification of the Wurlitzer Style 135, please refer to Organ ID #30880. The difference between the 135-A and B would seemingly be the trap compliment found within their specifications. Junchen's Wurlitzer book mentions the A, B and C suffixes as being indicative of what type of player mechanism was incorporated into a given Wurlitzer Unit Orchestra (aka "theatre pipe organ"). However, there are a number of 135's that are known to me that absolutely did not incorporate a player mechanism. In addition, Wurlitzer's model list only lists the Style 135, but shows that numerous examples carry the A, B or C suffix. Traps and effects present the one area where such small instruments might digress from each other even though, as 135's, they are shown to contain the same rank compliment.
