Spinning wheel ID

Not sure what I have here!
Spinning wheel/flax wheel? The time it was made and if it’s something valuable or just valuable to me!
Has letters PIB or possibly MB  imprinted on it in two places and has a double drive wheel.  The wheel it’s self is made in 4 pieces and mostly is put together with strips of medal and wooden pegs.
Husband gave me this  for our 39th anniversary because I love all things yarn related.  It was  in his parents estate, they were antique collectors planning on opening their own shop.  So he cleaned it up and repaired what he could but I think parts might be missing.
Hoping for some help from you all who seem to be very Knowledgeable about the subject.
Appreciate any input!

Yup, it's a spinning wheel. It looks (to this beginner) like all the main parts are there. Does the drive wheel (the big wheel) spin? If so, does it wobble, when it spins? You might have to look up the anatomy of a spinning wheel, too get familiar with all the parts, and how they work. Another thing that helped me immensely, was looking up my local fiber guild - they're an incredible resource! They also have a huge advantage over us - you can actually take the when to them, to get a more solid assessment, figure out what it needs, to get back into working shape - and teach you how to use it.
