Seller: preservationnow (277) 100%, Location: York, Pennsylvania, Ships to: US & many other countries, Item: 121908234080 ANTIQUE SHELL TYPE SHUTTER DOGS (HOLD BACKS) The main photo shows two sets each with a right and left shutter dog. These would be enough to do two windows or 4 shutters. All were professionally stripped of old paint through a heat and bead blast process. I myself do historic restoration hear in Pennsylvania and these were discovered here. I know how difficult it is two find original hardware you may need for your home restoration. I hope these are the type you are looking for. Note: the three small dots just above the shell on the arm which attaches to the base. There are slight differences in the design of shell shutter dogs and those with three dots is just one variant. I have some other sets list for sale on eBay where the arm doesn't have these dots and are just slightly different. They stripped clean and ready to be spray painted with primer and black paint. I will include 4 restored antique slotted wood screws for each.(The screws were cleaned using a device called a tumbler.) These are the type which would be mounted to wood siding.They are all in good condition and super nice. If you have any questions please write me. Thanks!
