I think most likely Mr Hoebig's second machine as spotted in the background of some recent-ish photos, though I do sort of wonder if that Wheatcroft man has sneakily got some parts more together than thought. He's certainly been running a lot of restorations in the last few years. All speculation. Though there's certainly going to be a few more complete Tiggers soonish, bitsas and otherwise. Funny as it's been decades of saying 'six' when survivors discussed.
Yeah. Hmmm. Quite possible. Reddit - Comparison between the Militracks Tiger and Hoebig's second Tiger
Another bid for Hoebig: Militracks Mystery Tiger: What We Know | PanzerPlace Might have to look at the Aussie rebuild too. Can't remember the spec, but he's certainly got the cash to pop over to Europe with one for an event he definitely attends.
Someone send me these pictures of the arrival of the Tiger I at Overloon; seems it has been assembled from parts of several (six?) different Tiger tanks and has no engine, so it cannot move on its own.
Possibly of interest: the folks there connected three SdKfz 9s and towed the Tiger on the arena. https://twitter.com/SofiGaming/status/1659557387638800385
When even the Panzermuseum is a little bemused, I'm not sure we'll confidently work this one out until someone involved spills more beans.
