SIG 33 (Heavy Infantry Gun 33 in German) Bison was an SPG developed to provide powerful direct fire capability to tank troops. It mounted the large towed 15cm infantry gun with its wheels onto a converted Pz.I chassis. Alan, of St. Petersburg, Russia produced this eccentric tank. Although Alan kits are "short run", they definitely qualify as being at the top end of "short run" kits, or even the lower end of "mainstream" producers' kits. While not of "Big T" quality perhaps, with a little care a very attractive miniature can be made from this kit. Tracks are individual-link construction, a big advance over the "rubber band" treads seen in some "major" producers' kits. No figure included.
