Hi BBE.
Thanks for showing us your roman padlocks. You are correct in that we don’t as yet have any examples of complete Roman locks, although we do have many more Roman keys to add to that section. Most of the keys shown are lift and slide, would I be correct in that your locks would have been of the spring barb type but with a turning key? It’s nice that your locks also seem to depict a deity, have you identified them?
