Argh. Liar, liar pants on fire.
When I saw this machine I did a little research on it and discovered that his description was lifted from another ad. It's not that far from me, so I asked a question about it (though I forgot to ask if the shuttle was present). He replied and said,
"This is an antique machine which is fully functioning. This is a standard straight stitch machine. When i move the peddle the needle head moves up and down. The only thing missing are the needles which can be found on ebay if you choose to purchase them."
Then he replied again, and this time posted my question to the Q&A and cancelled the 2 bids he had. I suppose I could email him but do I want to deal with someone who lies?
