I have the very same clock in frosted pink. The glass is almost identical to that of Bagley, but as you say, this is not catalogued as a Bagley piece. I am none the wiser of its maker. The annoying thing, is that there is the remains of a moulded mark inside of the base of my example. It can also be noted that the mouldings are the same both sides. No doubt to make to easy work of fitting the clock at the distributors.
