Paul - the reed barrel alone is worth big bucks - and I mean BIG bucks in the region of $1500 to $2000 if it went world wide on evilbay. GS based (which it is) or not $5K + as it stands.
It will almost definitely have a 'roundback' frame which is less likely to break under harsh riding but I am not sure about what appears to be two huge gusset plates welded under the seat area for the usual rear shock stress points.
Try and get the Commer van thrown in, lmfao !!!
