AFAIK, there was a 32 but not a 32A. looking at this page it seems that the 32 preceded the 49A in the catalogue (can't tell which year it is) and that it was a single. All I can read is that for a double the 49A should be used. I also notice that the dust cap is the same as on my Competition.

I have written to the site owner asking him for info. I'll post what he says if he gets back to me.
