Some oddities did happen in the transition between Super Takumars and the S-M-C lenses. I have an S-M-C 55/1.8 without the lug and a Super Takumar 55/2.0 with one.
According to Gerjan van Oosten, the Super Takumars with lugs (product number 37107) were commonly supplied with Spotmatic 500s. The S-M-C 55/1.8 without a lug has the same product number as the Super Takumar 55/1.8 (37101) and is described by van Oosten as "a lens from a transit stage".
Cheers
Can't offer any suggestions about the immediate problem without seeing a pic of the lens.
