Physiotherapy Equipment Identification help

Hi, I have been asked to sell this for an estate but I need to know what it is called.
Can anyone tell me what it would be? It is labeled Bioflex PTW-6. It offers range of motion scales & adjustable resistance. Looks like you strap the forearm in and then curl & rotate the wrist/hand. I believe it is for pronation/supination mobility?
It needs a light clean-up but is in great shape! Thanks.

Looks like an older isokinetic type machine but a very basic one at that. It doesn't really have much value for resale. I would suggest donating it to your local outpatient department as it would perhaps get more use there
