I'm in big, big trouble. I've managed to loose one of my sister's knee blocks that i was borrowing. Can't seem to find anywhere that sells them online. Any help would be welcomed!
If you can get the thorowgood ones then they should do the trick as both makes use the simatree - other aspects of the design are similar too. If you still have probs then I would just call kent and masters and they should be able to help you out.
