Adjustable Bath

I have an old style tub feet and came with an adjusting to the edges. What is it?
The headquarters of the rails metal forming on the sides of the tub. The seat itself is made of wood. It is also due to adjustable metal rails on the bottom and can be tightened with wing nuts. I searched on the Internet and found no information. in it. I know what it's worth or at least some information.
Let $ 600.00, now an explanation. A new claw foot would be around 1500 to 2000, and have a little modern plumbing, and will be called a bath. PPL Many like new things, so they are willing to pay, others like the idea of time but will prolly his bathtub re-glazing, which cost several hundred dollars and a lot of work to move in a bathtub. Therefore, stay low in value, you may decide it is best if the condition is great, and I'll tell you the seats you describe very nice, is of value. The disadvantage is that the economy will lose, and the leader of the bad parts are the housing industry. I am a GC, and PPL are not doing much Moreover, as their values drop by double digits.
