D engines did come in diamond packaging.
The D13-7 engines in the green mailing tube were from 1971.
The D12-3 diamond pack engines were made on May 16, 1975
The D12-5s engines in the diamond packs were made on April 13, 1973.
All diamond packages have three nichrome igniters with a brown coating.
I don't really have an extensive engine collection, just a few rare favorites and some I would never launch - like the D13s!
