My Corgi and Dinky collections are based on the models I had when I was young. I probably started with Dinkys in the mid 50's with the racing cars and agricultural models offering great play value.
One Christmas my parents gave me a collection of six boxed Corgi's, the new ones with windows, I from then on always returned them to their boxes after use. Consequently the earlier models are often missing end flaps etc.

I added to my Dinky military collection when I had several given to me in my teens, which my friends had finished with, usually unboxed. There also came a few Corgi's.
Much later I started collecting models associated with my domestic appliance business. This was sparked by Corgi and EFE models of Hoover and Hotpoint delivery and service vehicles. With my interest rekindled I have added a diverse range of appliance based models and have bought several boxed original Corgi's and occasional other models that have taken my fancy.
