Its certainly not a gem!
It could be a good project for some one and it could be used as is and restored/saved as you go along, it will need lots and lots of work but if its cheap enough to buy in the start, say £500, then its worth a punt. But I would take the sellers description with a pinch of salt, unless all the welding has been done it is not solid underneath, far from it!
Bloody Commer`s!
