Lefton China Hand Painted Teapot

Hello!

I recently inherited several antique/vintage collecibles and have had a fair amount of luck in finding descriptions, pricing, etc. of my items thus far; however, this one has me stumped. It is a Lefton China Hand Painted Teapot with a Square and Compass Masonic Symbol. I simply cannot locate any details on it! Any and all help with this is greatly apprecited!
