Ok, brief history lesson greenfield was started by Theo Reinhold in 64-65, first hd8 produced in 1966. Somewhere along the line Theo's son Lewis took over the family business. A couple of years ago he stumbled across this forum and was very forthcoming with info from the early days, what he could remember as he was on a kid in the early days. Here is a link to the thread.

He went quiet after about a month or so, and hasnt been back here since. With you're company going into liquidation i suspect it would have been a hectic and stressful time for him, not much time for us fanatics 😂
