Unknown airframe window

[Mark_Pilkington]

Hello Folks,  and Happy New Year

I am seeking help in identifying this window frame?

The part number appears to have a XG4-8C- prefix?

Any suggestions as to its identity?

Are you sure it's from an aircraft? As a sliding window I would expect it to be from a flightdeck, but the attachment points don't look very sturdy to me.

From a boat maybe?

I used to fly on the old H-52's and they had sliding pilot/CP windows. It was a window within an assembly. As I recall, when you need to eject it for egress, the whole assembly jettisons out. These windows kinda look like they came from an old farm tractor cab??
