500 single wanted.

[graffian]

I am looking for a MSS,ES2, model9 or similar, basically a 500 OHV though I did consider a 16H and if the right MAC came along I would consider it.
I would prefer pre-war[girder/rigid].
I would like something that doesn't need a lot to be put on the road but if a big part[engine or frame] of the right bike came along I might well buy it, so basket cases would be considered.
