Here's a handful of old models I built, most while in high school. I'm selling these for $3.00 apiece, plus shipping. No guarantees as to workmanship or quality; i.e. sold as is. Really best suited for wargaming, not so much for displays.

The old Heller AMX 30.....

....Airfix Centurion, has several coats of paint, the latest in Israeli colors.....

...the old Airfix Leopard 1.....

and a white metal kit from REVIRESCO, a Sci-Fi tank for a wargame they made figures for (called "Starguard", more details here http://www.tin-soldier.com/sg/sgcatalo.html). Named the KRMT heavy Tank; painted for an Ice-world environment. (do not know if the Starguard rules and figures are still being sold, though).
