Not posted here for a while, so here's an update.
The fuel tank, rh chassis rail and rear wheels have been needle gunned and given a coat of red oxide. (Note the old paint flakes on the ground around the old girl! Not sure what paint it is, but it comes off in sheets, and leaves the original red lead behind).
The rh front wing has been repaired, and straightened out. It has had a new piece let in at some point in its life, and must have had a couple of pots of P38 in it!
Have also taken some more of the side panels off, and found even more rot in both the bed and the steelwork. Still not 100% decided on what to do with the bed yet. Any suggestions?
