I see you won the machine I started bidding on. I was interested in this machine because there is a step by step restoration thread of one of these machines on the home-barista site. So youll be able to get most of the information from there.
As for the asbestos issue. Youll need to find someone rated for asbestos removal. The owner should not have shipped the machine in this condition and it should have been mentioned on ebay. Im sure there are legal ramifications for shipping hazardous goods without indicating them as such. I think the best course of action would be to get a price for the asbestos removal and try to get the seller to deduct that price from the purchase price. There should be quite a few places around that can remove and dispose of asbestos.
The worst part is that the seller has put your health at risk by not alerting you to the danger.
It may have been that the seller wasnt aware of the asbestos inside the machine. Im sure there are quite a few people who never open up there machines to see whats inside.
At the end of the day, Id have the asbestos removed and then get on with the restoration. It looks to be a great machine in all other regards.
