Value of vintage Ideal Dispenser Pepsi cabinet Model 501??

[RioVerde]

I have an all original Pepsi Open Beverage Cooler Model 501 made in Bloomington, IL. Metal ID tag shows serial no. #1H-1303.   Cabinet dimensions: 36" tall, 49" long/wide, and 28 &1/4" deep. Front Pepsi logo embossed with 2 dots.  Can't seem to find any info/sales on internet for 501. Looking to sell this one but wanted some comparison values.  Thx.
