You've got a 50's Birmingham Hercules there, a nice little 3 speed. It predates gumwalls so if you want originality, see if they have some blackwalls instead. I think it looks better but it's your bike.
A little suggestion for you. You're on a list of bike nuts who collectively have probably forgot more about old bikes than most LBS's will ever know. So when the next bike comes along, post some detailed pics before you drop it off at the shop. Or just grab a (proper) wrench and start taking it apart for a light cleaning, maybe an adjustment or two. Collecting, fixing and restoring bikes like this is fun and rewarding. If your LBS is like most other shops, the bike will still require a closer look-see and possible overhaul.
