Ok, Seamus, here's a couple of other ideas ...
1. The GB owners club may have one in its tool hire scheme. This used to be run by some bloke called Steve Wynne

; but since Steve's taken himself off to New Zealand

, I don't know who's doing it now. So try calling Andrew Jones, the club sec. ... AND, thinking about it, I'm not sure that Andrew doesn't have one of the tools himself ...
(Assuming he's not on this Forum and listening in), Andrew's UK tel is 01274 410916. Or e-mail him from the DOCGB contacts list at
http://www.docgb.org/contact_us/index.htm
2. Tony Brancato may have one/be prepared to make you one/know who has one. But I know Tony is pretty busy at the moment. UK tel (01865) 891203.
Ciao
