For your consideration, here is a Frederick Post Yellow no. 1462 Slide Rule, made in the USA. It has wear on it and is a bit warped on one end. It move okay. All of the screws and springs are there. The slide moves okay also. It will be mailed in a box, for protection. Item pictured is the actual item up for sale and comes from a non-smoking household. (214.976v-.9bb)
