This vintage speed calculator came in a box lot of Atlas milling machine accessories. On the back it says it's a "souvenir" but doesn't say of what. Perhaps a trade or tool show. It says "it gives you in one minute: speed, feed, diameter, time of performance, decimal equivalents, and you can figure dollars and cents at your hourly rate..." I can't identify the material it is made from; it has an ivory like grain but I doubt it's actually ivory (seems a bit much for a "souvenir").
