​Denis,
Regarding the KCA - DCA prefixes, do you have a source as to why you think
this?
Here is what I have so far with a simple test at the end. I don't show is a
dict which contains more information about the year/model, its not
relivant. I am happy with how it is working, I hope to be able to decode
BSA, and other British or more generally vintage motorcycle frame and
engine numbers. BSA looks like a mess.
