I had to remove an old CI tub (not claw foot) to repair a rotten floor under it. In trying to hook up the tub drain I've run into a problem. The bottom of the W/O tee is too small for 1 1/2" and too large for 1 1/4" tail pieces, so presumably it's 1 3/8"?
Here's a pic:

There are threads inside the bottom of that tee. The only plumbing supply place near here suspected it might be 1 3/8" but had no parts to fit it.
Are there mail order places to get what I need? Options?
(I don't remember exactly what WAS there,but suspect it was plastic--basically forced on/together. Don't think it was brass as even if it had been corroded/unusable, I would have saved it to recycle.)
Thanks.

Replace the drain with a 1 1/2" one. 1 3/8" was only used for leg tubs.

If you're determined to save the old waste, screw an 1 1/2" PVC female adapter on the brass tee and use PVC to drop down into your trap. If it were me I'd cut the brass waste off and use a Watco PVC waste.

change the whole tub waste. from under the tub, cut thru the rubber washer that is against the tub bottom. the rest will fall apart.
if you are determined to keep that tub waste, a female adapter will not screw onto the bottom of that tee. it is a 1 3/8 tee, not a 1 1/2. mickey mouse might try some kind of fernco rubber coupling being careful to get the top hose clamp right over the bottom threads of that tee.
possibly a 1 1/2 copper by 1 1/2 PVC coupling???
as i said, mickey mouse solution.

Thanks for the options. I'm loathe to change the whole thing unless I have to--experience has taught me that with this old stuff it's ALWAYS worse than I envisage. 
It seems to me this is likely to work. What do you think?

The metal nut fits nicely on the outside brass threads. The clear plastic washer should seal against the flat (maybe 1/8 to 3/16 wide) lower surface of the brass tee. The portion of the plastic washer that sticks up into the tee is a bit smaller than the brass ID, but shouldn't make much difference--or I could cut it off?
Thanks again.

something doesn't make sense. your first post says 1 1/2 wont fit yet your second post shows a 1 1/2" kitchen tailpiece ????
if your threads are 1 1/2 then use what you have. just change that slip nut to an all brass nut. lather everything up with some grease before assembly. if you are concerned about the plastic washer, there are flat rubber washers available.

A 1 1/2" tail piece will not fit up into the brass tee. The 1 1/2" piece (not sure what it is called) in the last picture is not going INTO the tee, it is oriented down, as in the picture.
Hope that's more clear?
Thanks.

it was clear before. the piece you have butts up against the threads of the tee with a washer sandwiched inbetween.
as i said, use it with a flat rubber kitchen tailpiece washer and a brass slip nut.

Well, given its age, the amount of obvious corrosion, in addition to the rotten floor, not surprisingly there is a leak from the shoe. I'll change to plastic, as advised.
Having not done this before, I wonder if I'm likely to run into problems getting the new assy. to seal to the bottom of the tub, because of corrosion? Any things to watch out for?
Thanks.

use 100% silicone caulking under the flange and around the rubber washer that is below.

The flange keeps water in the tub and the washer prevents leaking into the ceiling area, NEITHER of which NEEDS silicone.

geesh hj, you may have the expertise to apply putty and properly tighten the shoe on an old (and probably pitted from corrosion) tub. but, the average homeowner does not. silicone will make a tight seal on the top and help the rubber washer seal on the bottom.
at least the D-backs and the red sox won't have to worry about losing for a couple of nights.
