Unusual location for stained glass

Can you guess where in Greenock you would find this beautiful stained glass panel?

It is not easy to see now because it is situated in the upper portion of Greenock's shopping centre - the Oak Mall.  This part of the Mall, at the upper eastern entrance is now closed off, but if you stand at the bottom of the escalator in the dilapidated lower east section of the Mall and look up you can just about see it.

Plans are underway (and have been for a considerable time) to completely redevelop this section of the Oak Mall and the surrounding area.  I hope that when these plans finally come to pass this panel will be saved and found a suitable place in the refurbished shopping centre.  You can read about the redevelopment plans on Inverclyde Council's website.

I could not find any information about the stained glass panel, but to me it looks like a shoal of herring which would give it a good Greenock connection.
