You could try asking on the
UK RV group email list , or the
UK RV web site , but the responses you get might be a bit biased
Mark1,
There's a group building an RV 9a near Coventry. They may also have access to an RV 4 and RV 6. You can find the details in a thread on the
PFA bulletin board along with contact details of the person running the group. Looks as though there are still a couple of shares available.
