Thanks guys for the replies! I might just be mixed up. That is always a big possibility.

I guess the reason for my asking is that in January 1932 the Model 551 Colonial Clock Clock used a model 51 chassis, but in June 1932 the same Colonial Clock used a model 52 Chassis. Why did the model numbers on the Chassis change?

I am working on the Chassis out of a Colonial Clock, but I would like to know if it is a 51 or 52.
