New one came in the mail today! Big ben futurua, made 1973-78, from what I can find only the big ben version is radium. Which further backs westclox stopping radium use in 1975, seeing the baby ben version was made in 1976-81.
It's been a while since I updated the collection, as for radon yes it's well within safe numbers. Still can't believe it was only going to be 16 clocks in total I would collect.
Got a few good deals this past week, the westclox spur is extremely clean. The trainer link from what I can find is a turn and bank indicator for ww2 flight training simulators. Then finally the telechron, when your boyfriend says he likes the numbers you get it :3
Mail day! Got this JAN-CW-IB22 radar spark gap tube. Seems to be pretty spicy.. into the military cabinet it goes!
