In the area that would normally have the two number stamp such as 82 that would indicate the year of manufacture, their is two letters, HH. I  think this is a date code. Any help in deciphering would be appreciated.
Thanks

Two letter date coding was started in 1977 with HH. Before that the last two numbers of the manufacture year was used.

You have a PM on this subject.
