This just in today. For the price of a pizza and a dozen wings I got this steel Gruen autowind running (20 USD). The back is Has a plastic window and I dont know if it came like this or it was altered either way it was very well done and I like it alot. Enjoy this pictures and any information you have will be great. Usually I can identify Gruen from the 2 three digit numbers in the case back but obviously this does not have that.
