FMC 4200 balancer help

[konas]

Recently I picked up used FMC 4200HS wheel balancer but I can't calibrate as the calibration slug didn't come with it, just wondering if anyone on here would have the same machine and the slug either for sale or even can supply the measurements and weight so I can machine one to calibrate the machine. It's a hand spin machine and John Bean 3.2 is almost identical, so I assume the slug from either one of them will work.
Any help or info will be appreciated, thanks

Old post but do you still need help? I just got a 4200 with the cal weight. Here's the dimensions:
1.97" x 0.753"
288 grams or 10.16 oz
thread is 0.445" long and is 5/16 x 18tpi

I'm looking for an owner's manual for the 4200
