Columbia Grafonola H 2 (?)

I recently acquired an antique Columbia Grafanola at a Flea Market. I believe that it is an H 2 but i'm not sure. The arm is disassembled but the motor is in tact. Does anyone know where i can get a repair manual for this or have information on how to reassemble it? This is my first attempt at anything like this. and I have no clue what i'm doing. I guess we all have to start somewhere.
