Please look at all the pictures (8-12 pictures) for details of this item. There will generally be a ruler in the last picture. I am not the original owner of the things that I sell. The items are in « as found » condition and may be damaged or missing parts. I do not typically clean or test anything unless it is stated at the beginning of the description. Please do not assume anything – ask questions before bidding/purchasing. I sell a wide variety of items and do not always know exactly what information a buyer would need. Be aware that the device you use may affect the quality of the pictures. A computer using the eBay mouse over zoom will enable you to see very fine details. Please check out my other auctions. Thanks!
