Looking to be pointed in the right direction for who will buy/take old Meccano, Hornby, model cars etc in Edi

Hi

I’m helping an elderly relative clear out their house and she has A LOT of old hobby sets that belonged to her husband, mainly vintage Meccano, Hornby and some old, model cars. I’ve tried a couple of local places and have been listing on Marketplace but haven’t had much luck so far.

Does anyone have suggestions for specialist buyers for this sort of stuff? a lot of it is packed in its original boxes and some have never been used and are still sealed. the rest is organised in old school meccano wooden chests and old biscuit tins with lots of metal bits and bobs that are used to build the sets.

I've got a room full of this stuff and even more in the attic and would appreciate if you can point me in the right direction on how to go about selling it all as this is a bit out of my comfort zone and not sure how to go about selling or giving it away.

thanks and really appreciate any info you can offer!
