Hi Ian,

You'll need the following parts, along with a 110v step-down tranformer.
Part No.    Desc.                       Page Ref. (From Bulletin 1184B)
181851      Gear 17T                    36
181855      Pulley w/40T Gear, 16T      36
182267      Motor, 50 Cycle Synchronous 36 39 40

I'm looking for the gear and pulley myself and have asked Mr. RTTY but am 
still waiting for him to get back to me.

The motor can be found locally here:

(I'm not the seller but have bought from them with no trouble)

Regards,
