That's what we started out with in the late 60s. I bought one my Grandfather used at the family estate auction. It's in great shape except some slight corrosion where the battery was left in it. Doubt there are any out there that don't have some corrosion. I was determined to buy my Grandfather's green box and it really scares me to think what I might have paid to get it. Luckily I bought it worth the $$.
