Hi SB Obsession,

As you would probably know from previous threads on ODK, the numbers don't help in dating a particular machine.
The Kirby Lauson (Tecumseh) engine doesn't help much as they don't have a date of manufacture as part of their model type and code as Briggs and Stratton does. wink

However, being a solid deck Model 45 with a Kirby, the earliest date it could be is early to mid 1968.
cheers
