I have an opportunity to buy my greatgrandmother's hand quilting frame (the full size with rollers and clamps) from a relative's estate. They're not giving it, but I'm willing to buy it. But I don't know how much to offer. I checked e-bay but only found new frames. I don't know how old it is. She married in 1902 and died in the mid-50s so it's from somewhere in that time frame. It's not fancy. I suspect greatgrandpa might have made it - which makes it even more special. Anybody have any ideas on what it might be worth?
