Thank you all for this information! I had looked on ebay and was surprised by what seemed completely subjective prices. My friend will be selling this for a benefit so it seems that the best idea is to have people bid on it. It does work, and I'm thankful for the suggestion to have a sample of work available, Also I will download a manual, sadly there are no attachments found. It's a beautiful machine so hopefully my bid might win!
Again, thank you all for your help!
