Allen-Bradley Co. Sewing machine Foot Controller

Found this foot controller in my mother's things. She was a seamstress and collected all things sewing. I am selling in case someone can use and for charity donations. I do not know if this works so it will be a project piece. This is a used item and is sold as is. Please look at pictures carefully. I will be happy to send more if needed. Some of the identifiers are rubbed off but I think this is what is on the top of it: PATD 177788 I will bundle any items that you purchase in same time frame. You will need to message me before you pay so that I can combine the orders and send you an invoice. I recycle packing. I will double box and pack carefully.
