1950 EL Oil Pressure Switch

[Chuck Odom]

Hi, will someone tell me exactly what an OEM oil pressure switch looks like and is marked for a 1950 EL? I want to replace a malfunctioning repop with an original if I can actually find one. I see there are a couple on eBay right now but don't know if they are exactly correct or not.
Here's my gal right here.
Thanks
Chuck
