The last register of bikes published by the VMCC was the 3rd edition, in 1991.
DYT187 isn't listed, but many club members' bikes weren't listed as people were cynical about misuse of information.
A goodly proportion of the published registers were never sold, even after being 50% discounted, and many went into the skip!
All sorts of inaccuracies within the register, but a good idea that could have been improved with work.
