It is mostly likely a #54, rebacked and reperfed. Look for signs of rebacking, which would remove or obscure the watermark.
The usual method is to sand down the paper to onion skin thickness and use adhesive to mount on a new piece of paper.

It could be a perfed proof with added constellation. Stamps of Trinidad have been forged by Fournier.

This is a Trinidad stamp clean-cut perf 14, with no watermark. It looks like scott #32 but the color is wrong. The color matches with scott #54 but can not find any watermark and perfs look too clean for stamps from that set. Any idea?
