Don, read the guy's question before replying :-)
he is not asking about Venture, but about Stamo engined
T61

If you did your homework you would have found that:
Scheibe SF 25B (45hp Stamo MS 1500-1)
in UK built as:
Slingsby T61A (45 hp Stamo MS 1500-1,without electric
starter),
Slingsby T61B (A with Franklin 2A engine),
Slingsby T61C (about 35 built with Stamo MS 1500-2
engine - with electric starter),
Slingsby T61D (A with Rollason engine),

and then further improved (spar design and 48hp Rollason
engine, etc) into:
Slingsby T61E (Venture MkII) by the way it is 1600cc
Rollason engine not 1200cc as you say,
Slingsby T61F (electric starter),
Slinsby T61G (one off with SL 1700 Limbach engine)
