So mold numbers on parts would be random on various Bulgy AK-74 rifles and kits, no matter their dates?
Thanks!
Mold numbers are like dies. They could have made 3 molds for lets say the front sight base and numbered them 1, 2 & 3. They could have used all three molds or maybe they only used one mold and as it wore out, went on to the next mold. No one really knows. The next step after a part is cast from a mold is the final machining. After that, they could all be intermixed and pulled out as need when the rifle was built. The assembly line worker does not know nor care what the mold number is so long as the final machine part fits and works. First part in a parts bin does not mean first part out on a assembly line.
Once again, mold numbers are just for quality control. If lets say mold #2 FSB's are giving a problem, they know only to inspect or look out for #2 mold number FSB"s. As molds wear out, the number is retired when newer molds are made.
Also, do not confuse a mold number for a revision of the part itself. That may or may not be the case and only tracked by the manufacturer.
Another fly in the ointment is that the Soviets supplied starter parts for early Bulgarian production and may have supplement all through production. These parts may present their own unique mold identifiers to throw things off if you do not know what you are looking at.
So in essence, you can not rely on mold numbers to date rifles. You do not know the sequence in which the mold number was implemented into production. Unless you have detailed arsenal records, you are shooting in the dark.
I hope you do not collect Garand's, because the will give you fits with revision numbered parts if trying to date or make a period correct rifle. :neutral:
