Here's an unusually pretty door hardware set, usually used for a closet or basement door, where the big, pretty crystal glass door knob is on the (living) side of the door that is always seen and the turn knob is on the other side, rarely seen, (thus no fancy hardware was needed).  This was very common back in the day.

Set includes:
1 large, rarely seen 12 point mushroom-shaped/domed crystal knob,  2" diameter, very pretty, clear clean starburst center.  Not all rusty like most.
1 large nickel/steel art deco door plate;  measures 7-3/8" x 2-3/8"at widest point.
1 - 1.5"  steel rosette for the inside door application
1 steel turn knob with spindle.

Everything cleaned up for you.
No chips, paint, cracks, crud, rust or other damage noted on the glass or anywhere else.
Glass center is clear and clean; not all rusty like so many I see. No scratches.  Feels nice and smooth in your hand.  2 very small nicks on top are of little to no consequence but noted for the record.

This hardware is old so it's not be like-new or perfect but it displays very well and I consider it to be in in very good vintage condition, consistent with age and use.  
Lots of pictures included; please review all of them carefully as they are a part of the listing.
I always encourage questions before buying; I am no expert on these and I want you to be happy with your purchase.
Actual age unknown.

A very nice set of door hardware for the money.

I can also offer a mortise lock with key for additional cost if you are interested.
