Hello, I have recently come into possession of a Oliver Model 22 (not sure if it's an A or B) Sickle Bar Mower. I don't know much about them, besides the fact that It was stored inside and was only just taken out when I brought it home last week. I was looking for any info that can be given on it? and also an Idea of what it might be worth? as I said it was always inside and as far as I know it is complete, It came with nearly an extra set of rock guards and two extra bars, with the teeth on them. 

I hope that someone can Help me!
