The Museum has ended up with a set of duplicate Railroad Prototype Cyclopedias. As you may know this was a premier modeling and prototype publication for freight and passenger cars. It is no longer being published. The copies we are offering for sale are in very good to excellent condition. There may be a scuff mark here or there, but they are minor and all issues are free of writing, spine detachment, tears, etc. Issues will be mailed USPS media mail. Shipping is extra.
