Bookmania by Mark Simonson

I don't know how much it could have been customized but the base looks definitely "Bookman". Your best chance is probably to start with Bookmania MS by Mark Simonson, "a revival of Bookman Oldstyle (1901) and the Bookmans of the 1960s, but with all the features you would expect in a modern digital font family."
Here are your /M, /B, /O, /R, /e, /s...

Hi Ryuk, I like the way you presented the glyphs. Note: link for M needs repair.
