Here's a september 1972 339 with "Colex" globe, that I bought today, I'll post it in the reference gallery tomorrow with some better pictures. Running like a good'un except that the check valve doesn't work properly. The ball bearing doesn't stop the air coming back out so I have to screw the pump down whilst keeping my thumb over the hole. Despite my best efforts, I can't get the valve out to clean either. It's here in company with my 237 and 295.
