Hi Polybus,
Just thinking about this, why not send IanOz a PM, ...he often has contact with vintage machinery and may be able to source one for you...Contact him HERE
Hoping this helps...
cheers

Please do not PM me asking for support. Please post your questions in the appropriate forums, as the replies it may receive may help all members, not just the individual member.
Kindest Regards, Darryl grin
