SLINGERLAND 7 PIECE CHROME SET CIRCA 73'

Here is a List of the serial numbers on the drums:

Rodgers Snare serial # D-37860

Slingerland Bass Drum # 134790

THE BADGES ARE SILVER AND BLACK AND ARE THE 1970-1973 STYLE. IF ANYONE CAN GIVE ME AN ESTIMATE ON WHAT THIS SET IS WORTH THAT WOULD BE GREAT. THE SET IS IN GOOD CONDITION, WITH ORIGINAL HARDWARE, AND MINIMAL RESTORATION REQUIRED. THE SET PLAYS FINE

A FRIEND OF MINE IS SELLING THE SET AND I NEED A PRICE ESTIMATE, ANY HELP WOULD BE GREATLY APPRECIATED THANK YOU
