The winder is clean and almost new. The winder is Leica #14403 and #14402 for the battery holder (4-AA's). This winder fits the MD-2, M4-2, M4-P, M6, M7, MP, etc. It shoots about 2+ fps.
Both the winder M and the battery holder were made in Canada. I put it on my M6 a few times, but never really used it. The original box with the original $649.95 price sticker and inside Styrofoam are all included. $175.00 PayPal included. Shipping $9.00 in CONUS.
