Vintage Pair Of Handcuffs 1800S Arankin Phil

This is a cool old pair of handcuffs, they are in remarkably good condition everything works just fine they are complete with there original key, when these bracelets are locked on there isnt much wiggle room thats for sure, these are from the days of territorial prisons, they both have a makers mark on them which reads, a rankin phila patent dec 10 18? I cant make out the last 2 numerals without cleaning up the metal i will leave that up to the new owner to do if they wish, shipping will be 5.50 priorty i accept all forms of payment, thanks for looking!
