Cat D343 Diesel Generator question

Hey all,


I just came into possesion of a 175kw Diesel Cat generator (model 2842-0-815) (type SER-R) with trailer and cover. Runs great with 287hrs. I have no clue what year it is. How would I find this out? the serial number? (A33195TE)

I need all the help i can get on this thing. Anybody have any clue what it even goes for?

Thanks
