Open to debate that one, Frank.
There is a school of thought that there was only ever one car with 4-4 designation and all other 4 wheelers after that were 4/4. Allegedly the reason the 4-4 designation continued to be used was due to motoring press at the time and in later marque history books whether sufficient in depth research had been done...
However, whether we will ever find the truth of that with so many years having passed is doubtful.
I will follow the politicians on this on... and come down firmly on the fence - either designation will do me for pre-war cars
Cheers,
