Watermark and type check – If you have determined that your perf 10 coil is rotary and type III you will need to check for watermark. The type III rotary coils are a little easier than the others in that they are relatively common and there is no type III stock from which to manufacture fakes. Care must be taken with joint line pairs, however.
