Slightly off topic:
I acquired a Williams Base Hit in 2005 that could use a better backglass. Before buying it, I went to Shay's site and saw it on their list, but it was shown as "out of stock." I bought the machine on the assumption that it would likely be back in stock fairly soon.
Sixteen years later, it's still out of stock, and has never been back in stock at any point during that entire time. I've emailed them numerous times over the years to inquire if it will ever again be in stock.
I've never received a reply to any of my messages. I long ago gave up, made my own repro, and moved on.
