He had a meltdown and disappeared from the scene owing people money and books. Others helped mitigate some of it by trying to sort it out.
Vault was a UK based auction site that wasn't a focus for US collectors. It was therefore a good place to pick up keys. I bought a restored MP 8.0 Tec #31 for $5k when market was more $9k.
I thought it had to be something like that, you dont just pack in after building a business up like he did, i did here murmurs that people did not get big money books back, i thought he would never do anything like that, just goes to show, you never can tell.
