Just wondering where we can date the first centre port from. I bought my Mk 1 Wessie in a godden longtrack frame from Don Stafford in March 1978, have the receipt for $2200. and is stamped 77236. I had a 2 valve Jawa at the time also, but was able to buy a centre port diamond to fit the wessie in for speedway. This must have been around late 79 i think, but cant be sure. Still have the diamond but uncertain if it has a date stamp. (memory is like my riding ability-diminishing)
