1945 -55 Pennwood Embassy Presentation clock

I find these from time to time on various sites, this one was in the FB Marketplace. It is a Pennwood numechron presentation clock based on Pennwood's 751 Embassy style. I know it is a presentation clock because of the glue on top of the case. The plaque is missing but the glue lingers on. I have a second presentation clock by Pennwood with plaque intact, there is another difference, the end pieces on the end of the clock case are thicker.
