I've received two requests for copies of that photo';  coincidentally I purchased the "perfect" scanner (scans large format diapositive in addition to the usual), so I sent them attachments.  If there is enuff. interest and a volunteer to page them ,I'll send it.  I can also scan the photo's of teaching apparatuses from the Patrice Lumumba U.

P.s. I'll ask my Russian friend your question.

The Russian team attempted to build such a device to help their amphibious vehicle climb over rocky terrain.  They eventually abandoned this plan, but they may have been inspired by the device you mention.  Does anyone know if they are common in Russia?
