These look to be 1940s or 30's with great patina and shabby chic wear.

As an 80 year old object there is some wear as one would expect but all part of the character (see pics)! 

Three of the handles have clear gold paint work with one handle slightly more worn than the others. 

These are full sized door handles approx 5.5cm across and heavy being solid china. Original spindles are included. 

Good luck bidding
