hi guys just seen this on ebay,

http://cgi.ebay.com/ebaymotors/1938-196 ... 06.c0.m245

reckons that its a speedo drive for a 45 , but to me looks like one for a 4speed big twin, any one want to have a look?

Not for a 45 solo model. BT or servi only. Pa

That is servi only. They have reverse wound teeth and have the grease slot and hole.
