Can anybody read (or more likely recognize) this? The middle of the mark is Glasgow and I believe the bottom says Pottery works, but I can't read the name, McBundy's maybe?
Here's a water cooler that i picked up at a yard sale not too long ago. Note the similar glaze. The mark on this appears to match yours though I couldn't get a good pic of it,and it's hard to see your close up. Mine is also hard to read but after a few searches for partial names, I figured out it is Port Dundas/Glasgow/Pottery Co. The style of the mark on mine is exactly the same.
