Sort of...

I remembered that the Amiga has an odd number of pins (by today's
standards at least), but forgot that it was 23 rather than 37.

I thought I'd heard of a 37-pin FDD interface somewhere though... could
well be the DC37 you mention.

I seem to remember some of the old Amstrad PCs had unusual Centronics-type
connectors for attaching an external FDD. Would this be related to/the
same connector as DC37?
