They will need a good clean up and there's two minor pinholes on one of the units (see pic).

A spot of weld would sort that easily enough.
Other than that they will be fine with a scrub up and a pit of exhaust paint.
Was thinking of £40. Any interest before they go on ebay??
Do you still have these and are you doing Volksworld Show?
