Court Case Regarding Prints/Paper

Hello,

I'm the owner of a film lab and was recently contacted for information regarding some prints, and if their validity can be proven for a court case. Here is a link to some pictures of the prints:
I'm curious if anyone can help identify:
-what printers might have made these printed date marks?
-are these papers now discontinued?

Sorry, but I cannot help you in these questions.

The date stamps on the blank (non-maker marked) stock are those of the processor/photo lab who printed the shots - fairly obvious date stamps. The dates on the Kodak stock are manufacturing ones.

Thank you for the replys so far, I appreciate them. If anyone else comes across this, do you happen to know what machines would be able to print on the back and if there's somewhere I can go to look at when paper stocks were discontinued?

In photo 145732900 the following shows "MAY921561 NNN 1A"
My understanding is the date it was printed May92.
The 1562 looks like an order sort number, so the correct prints were packed with the correct order.
The NNN refers to colour corrections. N meaning no correction.
1A suggests that this is the negative number.
It is hard to know what machine printed this but I would guess it WASN'T a Fuji.

In photo 151029870.
100_0457.jpg is the digital file number.
The 3006612 is probably a sort number.
The web address is fairly straight forward.
The 2017-05-08 is the date the print was made.
I would guess this was printed by maybe a Fuji Frontier.

Hope that is of some help.

This link should help with identifying paper stock years. If you scroll down, it shows different stampings and which years you would find them.

Kodak Color Prints

Thank you foc & skylight 1b-- I really appreciate it

Newtonville camera has been large camera store for a long time. The only Kodak processors of the day were System 20 and the high speed 3510. I would venture they would have leased/purchased the 3510 for the volume of work they did at the time.
