I'll try this with a different title.
I'm wondering about marking and stamps to find the difference in these two items.
BLU-14/B Length 95.6 inches 10.75 diameter and the BLU-31/B
Length: 2.40 m (96 inches)
Diameter: 28.6 cm (11.25 in)
BLU-14/B is
670lbs
BLU-31/B is
766lbs
The BLU-14/B was around before 1964
When did the BLU-31/B come to be.
