I have 4 antique glass shades from old houses in downtown Tucson; #1 is from the El Presidio Hotel which burned down in the late 1990's.
I also have a vintage - probably 50's - complete fixture.
#1.
7 rounded sections, 3 with decorative flowers, hangs from a central pole fixture $30
#2.
cream colored cone with clear glass top edge, hangs from a 3-chain fixture $30
#3.
cream colored flat round with clear flowers embossed along the sides, hangs from a 3-chain fixture $30
#4.
white milk glass conical shape with clear glass edge near bottom, one small flaw near rim, hangs from a central pole fixture $25
#5.
large round frosted and clear glass shade includes fixture with central decorative glass, chain, and ceiling fixture $50
#1-4 do not include ceiling fixtures
All are in very good condition for their age except #4 which has a small scrape near the rim
Note: If you are renovating a 1900-era home, I also have door mortise locks, glass doorknobs, push button switches, and a clawfoot tub shower curtain ring assembly
