Vintage Arrow Electric Ball Clock Machine Ball Bearings 1981 works with box For Sale

This sale is for a super cool vintage Arrow Electric Ball Clock machine with box and instructions-the sheet is dated August 1981. Base without lid measures approx. 10\" across and 6\"back to front. It is 8\" tall with case on. I did replace the gears in the motor, as almost all of these clock have a rubber piece inside the motor that dissolves over time. I took great care and time into the process, watching a very helpful online video (thanks rick) and cleaning and re-oiling as instructed . Now the clock works great. It has all of it\'s parts, instruction sheet and balls. I did slighting mar the cover of the motor when taking it apart-some of these clocks have motor boxes screwed together for easy access, this one did not-it was glued shut, so I had to pry it open to replace the gears. I tried to do the least damage, and when this is assembled it is not visible anyway.. The clear glass case has some scratches, but luckily they are mostly on the back side. The inside parts and base have no cracks or breaks and is complete. The instruction sheet has wrinkles and tears. The decal sheet or letters is complete-but the F\'s have some fading and the pendulum sticker has already been applied. Has all 30 silver balls and 2 black ones. Box has wear-the whole top flap has been re-taped back on and there are dings and wrinkling. I assembled this for photos and testing, but I will be taking it apart and packing the parts with care for shipping-then you get the fun of building the clock!
