Original Gearbox Installation

[GEE56]

Can anyone assist with a contact at Catalina that can advise me what gearbox was fitted to my yacht when originally built? The engine is a M-35B and of relevance is whether a HBW50 or HBW100 gearbox was installed.
Thanks

But, that information should also be on the transmission itself.

and to make matters more interesting Hull 418 has a ZF-15-MA tranny installed. Appears to be original.

Thanks for the replies. Warren Pandy has been most helpful.
