Julian98 , Rollerman will be able to answer your question.
RoutemasterNL , your question is rather apt for what I have been discussing with my wife, my collection has taken over , it spans my whole life of nearly 54 years, I have around 35 pedal cars , 7 Raleigh Choppers, many many large scale toy cars, a massive plastic collection as well as a mountain of all makes die cast, I also have various other toys including dolls houses.
My dream was to have a museum but as life ponders on I have to realise that this will never happen , It was a nice dream though , I have never thrown away any of my toys , I once sold two Austin J40's which I truly regret , swapped a couple of Sharna pedal Rolls
Royces but apart from that I still have my life in toys. Which sadly are boxed away & taking room up. I don't have the bottle to sell but I get pleasure on showing my collection on here , which one day I will get my boxed Corgi/ Dinky toys out from the late 70's / 80's & show on here.
