Yes it's a merc....if it has an original ballast....this model ONLY came in mercs....This is the GE M-250R verison.....
The HPS in Chicago currently are the GE M-250R1 and GE M-250R2 and GE M-250A2 versions while this one is the 60s version also I kinda see the coated lamp in it...
I have seen a few in MD...usually on a barn building....
