HELP! Identify These Air Forks On A Nishiki Colorado Cunningham Design

Greetings, I'm new to the forum and I need some help. I recently bought a Used Nishiki Colorado Cunningham Design Bike. The bike serial number has only Five Digits. I'm trying do find out the Make & Model of the Air Shocks so I can get a seal kit for them. The shock shaft is 24 mm in diameter & the serial number on them is 115626317. What happens is the with leak down on air & a little oil. I have not taken one apart to see if it's simple O-Rings I need to replace of more complicated seals I need to retain the air. When I first got the bike the retaining caps were loose showing no maintenance. I tightened them and the oil leakage stopped but it still has a Slow air leak. I checked the Schrader Valves and they are not leaking. Any help you can give will be Greatly Appreciated. Thank In Advance For The Help....

Marzocchi XC400 from the early 1990's, maybe from 1992 or 1993.

Parts will be hard to find, Dr-Marzocchi in Germany has some service manuals and service kits for those old forks but his website is being rebuilt at the moment.
