Brandon,
Welcome to the QB Vintage machines forum.
First, I can't give you a price to ask on that machine, I've not seen any in this area as nice as that one.
Second, please rethink selling that machine. I know, you probably have no interest in sewing, but try it, it's fun. It really is.
Third, that machine is a link to your families history. Once it's gone, it's gone. Nothing can replace it, not even a machine just like it.
Now, Let me tell you a bit about me.
I'm a 61 year old guy who has just recently started sewing. I watched my mom sew from the time I was a very small child till she died in '01. I have her old HOTHER 15 Clone machine, my avatar pic, and use it.
Her other machine is languishing in a dilapidated shed in AZ. I want it badly but I can't get any of my relatives to get it for me. I've been told I can have it ( long story ) but no one will pick it up and ship it to me even after I've offered to pay for the supplies and shipping.
I've been watching my wife sew for 30 years.
Back in 1998 my late cousin gave me a Singer treadle machine we saw in an antique store. It sat in the garage and storage locker for over 12 years until late 2011 when I got the interest to try it. Since then I've caught the bug.
I have 4 functional treadle machines, one who's cabinet is under repair and two treadle heads I'm looking for cabinets for.
I use them all now and again to make quilts, shopping bags and other things.
My grandmother who I lost in 1988 had a Singer treadle. Nobody knows what happened to it. I'd love to have had the chance to get it.
My oldest aunt has her grandmothers treadle. I'd like to get my hands on it, I doubt my cousins would be interested.
Family history is irreplaceable. Take the time to gently clean and oil that machine, put a new belt on it, and learn to use it. Many of us will gladly and freely help, all you have to do ask.
You'll be surprised at how much enjoyment you can get from creating things.
And it's soooooo much fun to show the ladies something you've made and watch the disbelief on their faces. Especially when so many modern women don't have a clue how to sew.
That's just my opinion, freely given by a sentimental old guy who's seen so much family history vanish.
