Last clue:Two reel models, pretty much the same basic design, one associated with 'Braveheart', the other with the song 'See my baby jive'
If nobody gets the answer from that, it's simply because you've never come across these reels.
They are actually much rarer now than I thought
but are, I believe, still available made to order.
So probably not a good 'General Knowledge' question ...... sorry!
