Help with ID'ing furuno cover

[ReBait1]

I have a Furuno plastic screen cover. It measures 7 1/4 " WI AND 7 1/2H....DOES ANYONE KNOW HOW I find out what unit this covers? I'm going to sell it on eBay with a little bit of luck,,,,,,

Old blue Furuno lettering so it is most likely a model from 15+ years ago.

Yeah I figured, still it might have value. Thanks

Must be an old 1700 series radar??????

I tried everything. The size is so small I can't imagine what it could have been. Seeing that all old furunos had buttons, mostly on right side, a 7" cover seems to imply like a 5" screen.....

So I went back trying to search by specs and couldn't find info in an easy to review format. We might be talking last millennium.

I guess at this point it's just a collectable!
