I'm not convinced that all Hummel figurines have an incised M.I. Hummel signature (see below), but, nevertheless, thanks for the input.
The last figurine I posted I found listed online as a Hummel/Goebel and another as Goebel, both circa 1950. I didn't find one with the TMK-1 mark I have but I think now it's probably Goebel, circa 1930's give or take a few years.
I've listed a few quotes and references below. I've seen a lot more online not listed here.
"Look for the Hummel signature. Find Hummel figurines signed with an incised M. I. Hummel signature, usually on a vertical surface near the base. A feature article in Collectors News magazine shows a painted Hummel signature and relates that some abbreviated signatures are found on small figurines. "In a few cases, no signature is included," the Woodworths, authors of the book "No. 1 Price Guide to M. I. Hummel Figurines," report in an article in "Collectors News" magazine."

When the Convent and Sister Hummel made the historic contract with Franz Goebel, it was agreed that her signature, her personal stamp of approval, would appear on every piece.
It still does so today and the only exception is if figurines are without bases or do not have any adequate surface to display the signature. "

*Note: The M.I. Hummel signature was stamped or incised on all pieces that were large enough to accommodate it, but for pieces that couldn't - only the Goebel mark was used."
