Hi Craig, Good old British engineering and then they go and put a Briggs on it....Ye gads...what is the world coming to.....hehe

But seriously mate, if it is part of the Qualcast/Suffolk group, they are a very sturdy well engineered breed of mower, and come with a pretty strong pedigree.

Can you please post some pics, as we all love to see 'em.
BTW..I am pretty sure that the original Model 1450 ATCO cylinder reel bearings were double race also.
