I used to have a smaller civy version of a airborne A frame bergan that had a bamboo rather than steel frame, the sort of thing they were making emediately post war to use existing processes to make saleable good, like Enfield making wooden planes rather than rifle stocks.
Anyroad it was so neatly done that a friend coveted it to the point of obsession so I let him have it. Never seen another dead like it.
