As stated in an earlier post, picking the correct transfer for the Ajax is a minefield. For a start the model ran for nearly forty years so that covers three different monarchs. I'm not including Edward VIII as he did not stop long enough to confirm any Royal Warrants. Also bear in mind that the newest machine is now approaching fifty years old. There are many still around that are seventy plus ( and still usable ). As the transfer is just about the most vulnerable component it's not that easy to find an original, legible example. Even when one does, don't assume that it's necessarily correct as previous ' restorers ' may have applied their interpretation or preference. This can relate to any make, model and age. As with misinformation on the internet it leads to compounded confusion.
Here are the options, as I currently understand them :
This seems to be the earliest form I have come across, possibly to go under a Royal Crest, possibly not. Presumably for the mk 1 1933 - 1936
Believed to be for the mk 2 1936 – 1946/7
Mk3 for 1953 and a little later.
Later version mk3 for plate on cross-over handlebars. C. 1953 - 1958
Mk4 from c. 1958
Mk5 from c. 1964
Later mk5 from c. 1969 – 1972
I have identified at least three designs of grassbox probably relating to changes of mk number. I've also realised that there is likely to be a time lag of about five years from change of monarch to the time when the Royal Warrant changes. It is therefore just possible that a mk4 might turn up with a ' Late King George VI ' transfer.
Hope this all helps. There are inevitably one or two gaps and I'm keen to hear from anyone with a different view or additional information to add to the pool of knowledge.
