Yes, its a Tamiya Tiger that I built as a Late steeled wheeled Tiger (JUN 44). The steel wheels I bought from ETO last summer, I beleive that was their last set. But you can get them still from Wecohe. The small idler is a HL, I modified to fit. The small idler is a little narrow, it could be about another 2mm wider but for now it is working fine. I have not tested it with the metal tracks, but so far it has been running fine with the kit plastic track. It does take a lot for the track to jump off the idler, which I am more than a little bit surprised about. I was thinking the opposite would happen.
