[Yeomans22]

does this sound about right

 

theres a star at each end of the number too.

 

*S190813*

 

or possible

 

*SI90813*

 

its hard to tell as its been painted, i have put some tac power on it so i can read it pretty well, but the second number could be a 1 or and I

 

taking the log book to get updated next week so need the new engine number

 

thanks

i think it must be ST at the start now, as they never had an SI and they all had 2 letters first.
