Leyden Jar update:
Rico has just published the open source Leyden Jar diagnostic tool. Now all the project files are ready for future development work to add support for additional keyboards, maybe even non-Model F / beam spring keyboards!
https://github.com/mymakercorner/Leyden_Jar_Diagnostic_ToolThere was a discussion on lost/stolen keyboards over on DT. At least one board did end up being returned which was listed on eBay. The seller was a third party that did not realize the provenance and was fully cooperative. Even if the serial is defaced that would be a giveaway that the board is suspect. I log who gets each serial so I can confirm the board is ok. Some people thankfully have been contacting me to check that a particular listing is legit.
I believe here is the list of currently lost/stolen keyboards, though it may not be 100% correct:
F62 110
F62 127
COMPACT F77 72219** (last two digits hidden for privacy)
F77 1142
F77 225
F77 1155
F77 1849
F77 208
COMPACT F104 11
COMPACT FSSK 193
