Keep and eye in this "flea market", eventually a Baur KG-13B grip or a real L-39 grip (Russian copy of Kg's) appear there.

An option is try with Cheeb2006 the availability of one, their version is good as - if not better, than Baur.

The guy there sell VKB KG12A grip, what with some DIY - replacing VKB proprietary electronics (and connector) by shift Register or Diode Matrix can be used in other joystick bases.
