DIG import SKS-30 with 25 million SN

[firstchoice]

I saw this through one of the Auction posts for another SKS. This is a listing on gunsinternational.com:

https://www.gunsinternational.com/guns-for-sale-online/rifles/sks-rifles/norinco-sks-rifle-with-detachable-mag.cfm?gun_id=102533326

The DIG-imports of the SKS-30 are a bit rare and not posted often. BETA ARMS and China Sports had the lions share of the 1988 import of the SKS-30. They both used the "88" (import year) and then a 5 digit serial number on their guns.  88XXXXX 

The DIG-import on this gunsinternational.com ad uses a 25 million serial number. I hadn't realized that the Chinese were that far ahead of the curve to be manufacturing the SKS-30 in 1980 in preparation for 1988 exports to the USA. One of those smack to the forehead moments for me. Am I missing something or is this a correct deduction/assumption?  Or, were DIG's imports from receivers already made, and different from the new-made receivers for the other two importers?

I'd post the ad picture but Photobucket has been bizarre today. At one point, I had absolutely nothing in my account. Almost 6,000 pictures...gone.    That's disturbing, especially for the money I pay Photobucket every year. Wish me luck!

Looks like a 28mil serial 1983. Last known military production was 1984, 29th  (29 mil).

As i understand it, the sks30 are built on surplus type56 recievers., modified post ptoduction for commercial export.
