Early Western Electric/Tung Sol, Chatham Electronics 421a/5998, 2399 circa week 43, 1957. This tube has identical construction to the early WE421a having clear top, rectangular mica supports and bottom getters.

Testing strong on AVO VCM 163 where Plate Current/Transconductance are perfectly matched, and sounds great in my modified Bottlehead Crack with no issues.

PayPal fees on me, postage on buyer.
