I don't recall what a "T" is beyond the fact that they're allegedly rare. But if it "fits you to a 'T'... More power
My Model "H", a bit over a hundred Sn lower than yours! Integral front ramp is as yours. Your barrel 'may be' a bit heavier (unsure). Mine, pix below! About original but for Stith mount/scope and apparently sling swivel bases installed. I am impressed with what seems to me a fair & honest description in which your rifle, at least as suggested by the pix, is nicer than described. A happy contrast to most verbiage on guns offered up!
Congrats on your find!
Best!
