Classic 19' bathroom window model/serial

[bookerb]

Greetings,

I want to install a bathroom window in our 2011 19' but Escape is unsure which model window was being used for that year. If someone with this model year could let me know the manufacturer and serial number that would be great. I was told that the manufacturer model should be on the outside rim of the window and the serial number on inside.

Thanks!

Looks like the same window was used for all classic series 19' and the brand is Hehr so now just looking for the model number.
