This section is for the verification of toys that were produced by Keystone. The intent is to match each toy with a catalog, box or advertisement to confirm it was produced by Keystone. In time a “catalog” will be created that will have a Keystone model number and a toy associated with it. I have found that Keystone reused model numbers over the years. This was done with the wooden toys and there was overlapping of model numbers between the wooden toys, steel toys and film equipment/accessories.
