This is what I dragged home... the bike.

A May 1970 Norton Commando Roadster. The previous owner started collecting the parts you see here, for a Fastback conversion.

At quick glance, the bulk of the Fastback parts are there:

tank - missing the knee grip indents
seat- knee grips chopped
side oil tank
battery tray
chain guard
tailpiece
Tach and speedo were fresh from a rebuild.

Closer inspection revealed the rest of the parts were either missing or desperately needed replacing ... parts list

Many thanks to all those who have generously answered my pleas for help!
