1968 T120r Engine Number Question?

There should only be 5 digits in the number. I think the Triumph embossing on the stamp pad started in 1969. My guess is the cases got replaced and someone added the extra T at the beginning and 8 at the end. Maybe to differentiate between the original # and the replacement. Is there a frame number connected with this engine?

@darkman for this one mate

 

Numbers mean nothing to me sorry, T120 should be a block stamp and it's clear they have been individually stamped but the font is correct. TT was only used from 66 to 67 for the T120 TT competition bikes like i'm building at the moment and before 66 all competition bikes had a C after model stamp. Best bet is a dealer has done it for what reason i have no idea, as EJT said embossing on plinth from 69 so it could be any unit engine from 69 on.

I would say it's got a competition engine. Looking at the TT stamp I would clearly say the same stamp was used to emboss those numbers.

Factory TT's had a larger font for the T or C like in the pic of my 66 T120 TT Joe and it came after the T120 or TR6

I stand corrected and I for one would never dispute your vast knowledge.
