Okay, the answer is Francotte, built by Auguste Francotte Company of Liege Belgium. I have yet to confidently determine date of manufacture. If I read postings correctly on DGShop the SN indicates Bottom Grade (others are Medium and High) with a date of manufacture 1931. The company itself dates to 1805. If others can further enlighten, I'm all ears. Cheers, Jack
