Up for auction is a tone arm and elbow base for antique Columbia windup phonographs, with the original screw needed to secure it to the elbow. This part is very nice condition, with very little wear to the nickel-plated finish. It has none of the cracks or breaks common with Columbia phonographs tone-arm parts. The opening measures about 1 inch across, so this will work on various tabletop Columbia phonographs, and possibly other models  This would be ideal for anyone who needs the tone arm base on their old  Columbia phonographs or just like to collect old phono parts! I'm starting it at $5.00, with $7.50 for shipping. Good luck and thanks for viewing my auction!
