The Operation Time is 260 hours, Drum Run 130 hours, Tape Run 90 hours, Threading 150 hours. So, the use is relatively light.
There has never been any need of repair or service.
There are a few typical-wear topical scratches or marring on the lens hood and at the base plate area, but I would rate the camera conservatively as 'A' condition.
I have only run Panasonic AY-DVM63MQ tapes in the machine. I wouldn't say I have never had tape drop out on this camera, but I can honestly not remember any. I clean the heads for about 5 seconds approximately every 8-10 hours.
The serial # is 1112374.
There are 4 batteries + charger. 1 x NP-F970, 1 x NP-F950, 1 x NP-F770, 1 x NP-F570.
I have all the original bits & pieces that you can see on the B&H link above
