That is a vintage frame and I would snap it up just because of that fact. Have you seen it? Will it accomodate your quilting needs? Is it still functional? Many questions to think about but imagine you'd be hard pressed to find a gem like that again. If she hasn't asked for a specific price I would offer her at least $40.00 - $50.00 and see where she is with that figure. It it probably worth a whole lot more than that. JMHO
By the way have you seen the prices they're asking for those vintage wooden ironing boards? Unbelievable, and I'm still looking for one.....love those vintage items.
