Antique axle hub measures around 15" to 16" long and around 5" wide at the widest part of the oval part of the base. The bolt in the center is loose and if removed will leave a good hole for wiring if someone wants to make a lamp. Good for industrial art decor project or lamp base. I have another very similar to this one except it has S B on it and the number 3 10 on it
