[Mechanism]

I looked up the TH-14, it looks almost identical except the handle and dial. I thoroughly looked the case on myne over and there is no holes for a handle. I did find a PT-31 looks like myne but I cant find much let alone a year. I'm estimating 39-42 maybe? Myne is all original except the firecracker, and I used it every day. I have an appointment in June to have it gone through and rewired. I love listening to old black and white radio on it every night. Amazing that broadcast still come through loud and clear 80 years later, the local station is so loud I can easily listen with the volume all the way down.
