Gobsmacked to see this up FS. This was mine for over a year, I had it restored to original spec by Electric Wood (Wal) and can supply the buyer with the invoice for the work done (£1300 worth!), which they did to their usual fabulous standard.
Technically not totally original, though on the other hand it's golden era mid-80's Wal - I was told the handwriting on the control panel label was Pete's - but with the benefit of brand new p/ups and preamp, and 100% of the work has been done by Wal. I've played a good few Mk 1 Customs and this is in all honesty far and away the nicest playing and sounding. Can't say I remember it being particularly heavy, though no Wals are light.
Only moved it on to Chris as I had the chance on a 1914 Gibson F4 mandolin, that I'd have done anything short of murder to acquire ....
I'd predict fairly confidently that this is likely to be the last reasonably priced Wal that we'll see FS anywhere, and I'm currently counting my pennies to see if I can buy it back!
