Duplicate post from earlier but thought i'd update with a better title!

I recently bought a great 70s Viper from eBay, but the only problem is the low E tuning machine is cracked and taped up. I was wondering if anyone has a spare, or can put me in the right direction to find one! Below is a picture of the Schaller version, and I can post a picture of the actual one when i get home from work. (The actual has the old ovation logo instead of the schaller 'd')
