Guys - I would be grateful if someone could identify this piston. From an initial search on the web, it looks as if it might be for a 500cc Triumph, but I cannot be sure.

The OD, measured at the bottom of the skirt, is 62.75 mm (2.470") and the overall height (crown to skirt) is 68.93 mm (2.713").

The code cast on the inside of the skirt is E1908.

The numbers 005 are stamped on the crown.





I can take some better pics if this is not clear enough.

The 'E' part number indicates it is Triumph. The 3T model (350cc twin) had 63mm bore size. I'm surprised it has a raised crown.

Thanks, Aco. It would appear to be an odd-ball, but from what you say, most likely to be for a 3T.
