I assume he meant to link to
www.predicta.com which used to be the homepage of Telstar that made reproductions Looks like the domain has been sold to a new company.
They show up for sale now and then. Telstar did a very good job from what I've seen although the necks were longer then the originals. I wish they had sold the repro parts so we could replace the cracked, warped and foggy old protective screens.
I believe they were well over a grand when new. The used ones seem to go for around $500 - $1,000.
