Right...
Happy Jack's (which was subsequently mine, and is now with another BCer) is a Guild Mk I.
De Armond/Fender went on to re-release the Mk I with better tuners (not the friction type of the Guild Mk I). The Guild and De Armond are very similar, and are the Mk I.
Ashbory went on to produce the Mk II. This is what's being auctioned off - it's 22" scale, a different body shape, 2-a-side (and different again) tuners, and there were something like 73 made. However, there doesn't seem to be a huge demand for them despite their rarity - mine (good condition, a couple of small chips to the paint) cost me around a third of what this auction is starting at, and I was the only bidder. I have seen a neck/body sold a little while back (I think for somewhere round £100). They have been known to fetch silly prices though. I think there are a very very small number of natural finish ones, and I think they'd go for a lot.
