Thanks for all the responses.
The klicky may be from 3265x - Jousting Knights but his chrome armour could be from any Nuremburg knight set, like 3052 o 3291 or seveal others.
Sorry, I put the clicky in for size reference.
I have about 10 of the horse fence holders, so now I know where they go.
The "war drum" was a big mystery. I couldn't imaging a tankard of that size.
Thanks for the info on the yellow diving bell part, without having the helmet, I was at a complete loss as where to even begin looking for it. And since it didn't fit as a hat, I was clueless as for it's use.
So, the only mystery left is the orange piece.
