They had some of these on display in the commercial spaces at the Deutches Museum in Munich when we visited in 2003. Makes transition between shop and museum ill defined :-). Except that the V2/A4 was not for sale. Assembly instructions are amazingly good. Almost as good as a 1960's HP manual This for their coffee cup engine http://www.en.boehm-stirling.com/tl_files/stirling-technik.de/downloads/man= uals/HB6-assembly-instruction-english.pdf Senft would have been impressed. You could build one of your own easily from the assembly manual. I note nice touches like roller bearings in some places and extra touches like dust seals on sone side of bearing but not on other. No obvious regenerator apart from walls of displacer chamber and displacer edge. Seems to go well enough as is but a trace of regenerator should be even better.
