Amber blob top embossed 'M' on bottom?

Picked up a couple more today, people doing spring cleaning around here. The amber bottle in the middle is a slick except for the 'M' on the bottom. I'm assuming Marion Flint Glass Co. would make this bottle 1912 at the latest or am I way off? https://sha.org/bottle/pdffiles/MLogoTable.pdf

Here's another M, a little different shape and top. Might also try glassbottlemarks.com/bottlemarks-4

Being a blob top I would assume older then 1912. unless it's a abm blob top? LEON.

I agree. I know that my example is much older than 1912. That's why I suggested the other website.
