i've seen OV-50's in lots of parking lots,and the Cooper OVL's are common as dirt in alabama,the birmingham area also had some Crouse-Hinds OV-50's as well.
the Fins indeed had Cap's...and if you notice the Early AEL 327,Westy OV-50 and GE M-1000's,Revere 2700's all had Fins with them being eliminated in later generations.
Some fixtures also had up to 3 maybe even 4 caps alone! I know some 400 watt fixtures had 3 caps...so it's possible the 1000 watt would have 4!
There's OV-50s with fins near me...still proudly in service on a parking lot....now they just get spot replaced if one goes bad with a new mercury....not sure about today......but as far as I see..the replacements are GE M-1000, some OVX and GE M-400R2 all mercs...maybe some may be MH...I will have to check...
