Silvertop Engine year

[Porkeh]

Hi guys, finally picked up my td42 engine today, before I go ahead with anything, I was wondering if it is possible to tell what year the engine is, its a silvertop td engine number being: TD42 1004xx
Ive tried searching around the forums with not a lot of luck to be 100 sure of what year the engine is.
Any help appreciated
thanks alex

Silver tops were pre 94.
