Wow, that is gorgeous.
The answer that always gets under my skin is "It is worth what you want to pay for it." That is annoying, because you want context, reference, information. But, on the other hand, that answer is true.
The more I look around at these amazing machines and cabinets, I think; worth? Priceless. Is that really solid oak? Could you even buy those raw materials anymore? Even if you had the materials, how much would it cost you to have something made? Hundreds. Hundreds. So, that part of the Worth question gives it a high tag indeed.
The fact that these are not coveted or valued means that it may only fetch $50 - $200. (I am guessing!) Either way, in my humble opinion, a price like this constitutes at the same time a steal, a rip-off, and a sad insult to the machine that in its day cost probably the equivalent of $2000.
I hope I don't sound flippant. I just mean that if you love it, then I am pretty sure that unless you pay a Crack-Smoking-High-Price for it, you will be happy. :-)
