I bought 12 sets of these hinges when I replaced all of the interior doors in our older home with 6 panel doors. They are a very nicely detailed, heavy duty, brass hinge. The only real downside is the lack of a removable pin. I personally had no problem with that. You just have to block the door up while hanging it. At the price that is only a minor inconvenience. I would definitly recommend them!
Original 140 y.o. Hinges not as nicely detailed as these replacements. Wish hinge pins came out, since reinstall of door is tricky.
