Corona extendable saw

[Jared Minor]

Hello everyone. I'm going to be honest and say that I am not in professional tree care. I do have a great enjoyment for all things dealing with trees. Well, I was cleaning up a tree yesterday and the top part of the locking mechanism on my saw cracked. Does anyone know of a replacement part? Corona doesn't sell it, but it has to be made somewhere.

Any ideas?

Thanks,
