Hi Al, Mal and all,

Who will ever forget the Frankenturner!

I read this as the 'second generation base' - the 18" base introduced
after the first models - the 4m, 2A and 2M.

It was introduced for a clear reason - it could be fitted with an optional grasscatcher.
Al, you are lucky that yours has the side deflector ('windrower').
Turner were one of the first to overtly recognise design safety.

I think this model is a 4BIM (B = second base; I - Impulse start; M = manual throttle)
This has the Kirby GEB - meaning this machine would date between 1960 and 1964 (I think).
