speaking of triangles, i spied this tan leather wassily at goodwill the other day. i feel like i need to become an expert on how to spot the real from the fake so i did a little research and tis is what i found...
the end of the metal tubes should not have any welding, it should look smooth and continuous, if the ends have caps it's fake. recent models will also have a serial number and breuer's signature stamped on the base. the measurements also have to correspond to the original knoll
there you have it!
