pole barn window ID-need replacements

[Dutch445]

I am having a hard time finding out what windows are in this building, but the
sashes need to be replaced. Is there any chance somebody out there can ID
the manufacturer? there are no markings we can find on them, may not be
common. Located in the Upstate NY area.

Don't know if you tried to look in the corners of the window but I know Andersen Windows etch their logo in the lower right hand corners. You have to look real hard to see it though.

Sashes should pop out, I'd take one to a local window place that's been in business for a long time. They'll have someone knowledgeable who can probably figure it out.
