Just picked this up…the fella I purchased it off said it was his grandfathers (deceased) which he purchased from new…it was passed onto his Uncle who is now in a home, but the mower never left the property as it was originally his Grandfather house and his Uncle moved in after his passing…
Anyway doing my research it is a Model 31, but the motor looks like it’s off a 35 (Round tank) but I have heard that SB did a lot of odd ball things in their time…just wondering if this could’ve been a late model or last of the run 31’s before they went to the 35…hence the updated motor.
Just smells original to me with the experience I have had with SB reel mowers
