I really like the delivery scooter can you tell us more about these diecast?

These were made in Italy by a company called mercury in the 1950's. That is about all I know. I got them as part of a childhood collection I bought.

Those three sure have tons of old-toy charm, especially the scooter. Congrats on a fine purchase - I would've bought 'em, too!
