To the best of my knowledge, there are only three keys: the tubular 
XX2247 which is used on most -8s and -11s including my 8/es and 11/34, 
the one that looks like a filing cabinet key used on just a few machines 
(all keyed alike), and the plastic "key" used on later Vaxen as well as 
the 11/24 - albeit in a variety of colours of plastic.
