Hunting for Half-track (German) diagrams, etc...

Not sure whether to be surprised or not, but I'm haviing a tough time finding good plan view illustrations (diagrams really, top, front, rear, bottom, etc) of half-tracks, 261, 232, etc would be good... anyone have any links? I've found a couple of good armor books for them, but at $45 to $50 each, it's a bit pricey for sight unseen reference. Also, I've found it rather easy to find diagrams for the big boys (the main AFVs) but again, sites are woefully short on suppert and other vehicles. Seems to be an odd sort of trend in reference hunting.

Thank you...
