good morning! you go here, in the site of my friend Lila,Cannoli e tiramisù: http://www.ornato.it/?p=71 you will see your machine. (I have one, too), and you clic at the bottom of the page, before comments, where you see this:Manuale Necchi BF BFL (il manuale è un a compresso, per visualizzare senza scompattare installate CDisplay)Lila is going to explain you all about vintage attachments, zigzagger and buttonholer feet, hemstitchers etc.
so you you can embroider with your bf. I bought some from Lila, and some from US ebay where you find thousands.:o
look at the price! I saw for 400$ the same foot I bought in Italy for 20 €, ahahah:D. but there are a lot of good prices in US. here in Italy, we are a few with these kind of machines.
singer attachments are generally good for this necchi. they must be low shank saluti dall'italia:o ciao

Hi, I have an opportunity to buy a Necchi BF from the estate of a deceased neighbor. I have no idea how much to offer, assuming it runs. What do you think would be a fair offer for me to make? Thanks much, Mary

Ive paid $100 for each of mine and never regretted it. they are awesome machines
