G'day Sven and Mod BB
Many thanks Sven for the generous co-operation you have shown.
We have every reason to believe that the engine is original, but the
starter cannot date to the engine block or sticker. The original starter with
its Model, Type and Code has been lost.
Nonetheless, I have a match for 450511, mower number 1303, with a
10/75 engine build date. Given engine shipping times, that machine
would probably be a early 1976 mower build.
I speculate your engine dated from about the mid previous year for
a mower build after September, 1975.
I believe your machine is a late 1975 machine introduced as part of
the 1976 Model 45 range.
This means this is an early example of a Model 45 powered by a
Series 8 Briggs, and introduced for the 1976 season.
Congratulations.
