Hi all,
With this Mayfair with the slot in the base ,I have a 1969 Victa Corvette with the slot so (the slot under the cylinder)
I was thinking if the mower has a late build date in 1968 it would be the same as a 1969 model Mayfair.
My 1967 has no slot and the 1970 has no slot but 1969 does with the Corvette bases.
The Mayfair bases I checked all had no slot but I may not have a 1969 model.
Checked a 1968/1969 Cortina base and that had the slot.
Just saying it's likely that the engine for that base is original.
On the rear flap there is a riveted spring steel plate / that holds the flap open when not
using a catcher.
The double arrow hub caps are probably as hard to find as Pace caps.
Cheers
Max.
