Thanks Clint, here's the one I found:

So from the looks of things, this is
not the aircraft Tober flew on 30 January 1944 (which would then be R4+LS 750811 and fully destroyed in the crash). If Ed and Wikipedia are correct on the timings, then the Lichtenstein SN-2 indicates it's a later crash than Tober's, but not much later, as the photos still show a wintery scene.
