Any toy building collectors here?

I collect mostly UK made toy castles, western forts, ranches, western town buildings, farmyards & individual buildings such as cottages, stables, cow sheds, pig stys, etc., and zoos, zoo cage buildings etc.

My problem is that very little is known about which companies made what, most items being unmarked, and even those which are marked, such as 'The Willow Series' of toy farm buildings (made in the 1930s?), no one seems to know who they were.

Other companies I'd like to learn more about include Amersham Toys, Barton & Co., Debtoy @ Suffolk, GeeBee toys, Hugar (Hugh Gardener @ Epsom, & later somewhere on the south coast of England) & Pennine Toys (Manchester area?).

If anyone else here collects these things, and can add, or would like to exchange info about them, please give at least a token answer & add me to your contact list.

Of course, a detailed answer about 'Debtoy', 'Willow Series' or any of the others or similar would be even more welcome.
