This porthole has no markings so we are not sure who the maker is.

The porthole is just under 8.5" wide in total, and the window portion is just under 5".

The hinge works well and it is secure and sturdy with no broken pieces.

The glass and metal is in good shape with no cracks.

It does have the sealing ring, but it is pretty dried out.

Thanks for viewing! Ships in one business day!
