I've asked a few times if anyone knows where to get vents like
these, but this time I actually have a link to pictures - so that

The guy I would try first is:

Of course, you are certainly welcome to use our free want-ads at:

Also, if originality is not a problem, There are vents, typically used
for ventilation behind panels on board, which would suffice. Any large
