Don't think new frames are available but we can probably sort you out with a good used one. As for hoods, they are available new. Contact us at [email protected] (not by "pm" or posting a reply here please, you may not get a reply very quickly!)
A few years back I did buy a brand new factory frame (still in its original factory packing) with vinyl hood fitted for an S2 spider. Presumably made for US market. Paid £600 for it and was told that the official price was getting on for £2k.
