Could be southern yellow pine, I have some that looks very similar to this on some bits.Doesn't look like ordinary "pine" i.e. Scots Pine a.k.a. "redwood" in UK, but could be one of the 100s of other similar coniferous soft woods. Certainly isn't "quarter sawn" either.
Reminds me vaguely of cedar of lebanon. You can find all sorts of odds and ends of unfamiliar timber under coats of paint, in older buildings
My timber supplier (and many others, I guess) calls "Plain Sawn", "T&T" (through and through). Confused me when I first met that! (Just like, in my early days of dealing with computers, I never found any translation if those strange initials, "IT"! )Image shamelessly stolen from another woodwork forum:
