Today I found a 500D set with G1 handset (not retractile), and all [the] parts have matching date codes in 1953, and there is no vermilion paint or painted-over stenciling on the base. The dial also has a clear plastic cap that completely covers the hub and under which is the number card.
The all-bakelite handset and the phone's robust construction make it the heaviest 500 that I have ever held. How common are early 500s with all-original parts?
