I bought this thing at a thrift shop a couple years back for $25. A little beat up but I figured it must have had a lot of good use. Well I finally got around to tearing it apart. It was very dirty and had a broken mainspring. I tore it apart, cleaned it and when I found out my used k&d winder had worn out catches on them, our very own Michael madden came to the rescue for me and thru a few emails, Lol, told me how to wind it by hand. I sure thank him for his help!! Here's this ole' beat up Waltham that is running nicely now.!
