This is a Silver Butler “Electronolytic” De-Scaler for removing corrosion from an engine’s cooling system. I would consider this a “Gimmick” type device with lots of marketing hype! It is from the Butler Engineering Company of New Orleans, Louisiana and has a 1945 copyright date. The container is a cardboard type material and measures about 3” in diameter and about 6.25” tall. The actual de-scaler measures about 2.5” in diameter and 3.5” tall. It includes the instructions, warranty, and a tag with patents and a disclaimer. It is in excellent original condition as shown in the photos.

Shipping within the United States will be by USPS Ground Advantage. If you purchase multiple items, you can use the cart and request an invoice with updated shipping charges (works with some browsers only!). If that does not work and you pay for each item, I will refund all excess postage paid through eBay.

Please contact me if you have any specific questions about this item. Check out my other auctions for additional automobile and petroleum related collectibles. My eBay store is called “Vintage Maps and More” and I have been buying and selling on eBay since 1996.
