Just a quick update:
It's now over a year since I started collecting and seem to have ferretted out and acquired every bit and piece and every nut and bolt required to build a whole SL70!
Actual progress so far: frame bead blasted and repaired, then powdercoated in original colour (as close as can be),
fork stanchions newly hard-chromed, new fork seals fitted and reassembled, tank derusted, dents removed and etch primed, seat base (thanks Tim!) repaired, zinc plated and painted, wheels disassembled, hubs polished new rims and spokes fitted. That's about it for now.
I'd say another year and it will look like a real resto!
Let me knwo if anyone is interested in photos of the work in progress here...
