... a never to be released prototype in the catalogue?
This is certainly a possibility,
Garry. Especially since the shoes were weighted to keep the diver under water. The shoes may have been just made of metal (much like the Playmobil anchors and pulley hooks). So, it would have made sense to do the helmet in grey to match the metal shoes.
Could it have been a Playpeople only release?
Good thought,
Bogro! However, the 1984 catalogue cover that
Garry posted confirms that Playmobil had taken over from Marx Playpeople. (1984 was also the year that I was fortunate enough to have met Norman Brown who was the President of Playmobil UK. So, I can also confirm that it was no longer Playpeople.)
Added it to PlaymoDB, Richard, hope that's OK.
Of course it's OK. And,
Heather, you never have to ask. Any information I have is yours for the taking ...
All the best,
Richard
