My "new" Clark Forklift need help

[W&K AUTOMOTIVE]

Just picked up this little older model Clark propane forklift. I'm guessing 60s era, but there's no data plate on it. It actually works pretty well, 12' lift, tilt, brakes work. I haven't even looked yet to see what engine it has. Runs well, good oil pressure, and doesn't smoke or anything. Any guess as to the model or any more information. Previous owner was essentially gifted it when he moved into new shop. We believed it was 3k capacity. Also, anything on maintenance, etc.? I paid $1200 and feel I did ok.

I am sure someone will chime in, but for reference or more information there are special interest forklift groups on Facebook if you happen to use it. I have seen a group for Clark owners before.

It's new enough that it has a roll cage (or someone added a roll cage.) I don't know when they became mandatory but it was after I had a summer job in 1976 during college driving one.
