Hmmmm, an unfamiliar bourbon, and a familiar gin. I like Maker's Mark, but don't know how it compares to Town Branch. I'm not into the more floral botanicals gin, like Tangueray (the best way I know of to ruin a martini), instead preferring the more traditional such as Bombay Safire Blue. We might agree on the vermouth, it looks like it could be Martini Rossi.
I quite like your Spirit Locker, cheers! 
This table is from my father-in-law’s house (passed down from his father-in-law as things turn out). After he died, not one of his children wanted it so I got it. Many a time over the years I drank from this little bar so it has a good pedigree. As for Town Branch, I’ve never tried it but will do so tomorrow on my birthday. The liquor store didn’t have any of my favorite bourbons - Old Grand Dad, Wild Turkey to name two - so I tried something new. As for Maker’s Mark, a pal of mine swears by it but I find it too smoky for a regular drinking whiskey. Finally, martinis - that is indeed Martini and Rossi but it is there for my guests. I drink my gin straight, shaken not stirred (!), so it may not even qualify as a martini. I do like some fruit in it, an onion, an olive or a lemon peel twist, but never all three at once!
