Eric, I bought the kit at the Shizuoka Hobby Show this past May, and it was a special event-only packaging. Now, however, it's supposedly a regular item, although I've only seen them at
Tamiya World so far. And at about 10 bux US less than what I paid at the show!!! Those chiselers...Don't know about overseas releases. Tamiya will be selling a T-55 with the Friul trax as a built-up in their Master Work Series.
Chris, I haven't built 'em yet, so I don't know how many links. No indication in the Friul instructions! I'll probably just use the Tamiya trax as a rough guide, and then just add a link at a time till I get the right amount of Soviet Sag.
