Sorry, I thought you were joking with me so I joked back.. :)
I do think that with this simple design parts won't be much of an issue... It has not needed them in close to 100 years. Just not a lot to worry about on it if you keep it well greased and don't beat on the wedges and crack something. I have used it nearly daily for the last 8 years with no issues other than one easily repaired leaf spring when I first got it...
