I have a combi that's surplus to requirements. It's a Sovereign, and has a rounded cradle suitable for a Lark, Firefly, Albacore, Finn or suchlike. The road base is in excellent condition but the trolley is a bit rough - tho' serviceable. £100 seems fair. Call me on 01252 311982, I'm in Farnham, Surrey.
Regards
Nick
