Monday Finds and Plea for Pattern Help

I had a business lunch with a fellow blogger, The Chilly Dog (who is an amazing crafter) in a different part of town than my usual haunts. So, it being a different I thought I'd pull into some random thrift stores on my way home. I'm glad I did!

Here's what I found...I guess my thrift store drought is well and truly broken!

Starting clockwise from the bottom left:

• Divided 1-1/2Q Town and Country with lid, $4.75.
• Divided 1-1/2Q Charcoal Snowflake, with lid, $10. Yes, expensive, but I found this at a used bookstore that also has all sorts of random items folks trade in or sell. I had trade credit so I bit the bullet, technically making it "free" to me. The store had a lot of other Pyrex but the prices were crazy considering the condition for some. I feel slightly crazy myself for getting this piece but I console myself with the knowledge it was free, it just cost me books I traded in however long ago, as I have been carrying around the trade credit slip for a couple years now!
• Gooseberry 472, $3. I couldn't pass it up.
• Mystery 045, $5.50. Both this and the first item came from the same store and were 25% off.

About the mystery piece: I can't find the pattern anywhere, not in any of my reference books or any reference sites online. It is for sure Pyrex, but what pattern? Does anyone know?
