Hello Frank66 and vccomm,
A big warm welcome to the ODK Forum

We all like to tinker and learn here.
Now as far as the model 45 is concerned I could send you somewhere where I know the operator is top notch but of course will charge for his services, or alternatively I'm sure I could help you out depending upon where you are located in Adelaide.
Your reel will most definitely have to be re-machined along with your bed knife, but only a good look will determine what needs to be done.
If you could post up some good close up photos of the damaged areas on both components I will be able to advise you in a much more definitive manner.
For now,
Cheers,
BB
