+1, Quill stems are sized based on what they fit, not what they are. 1-1/4" steerers (take a 1-1/8") stems are extremely rare, and you may have difficulty finding one. If you think you've found one, be sure to cross examine the seller to make sure that you're getting a stem with an OD of 1-1/8" for a 1-1/4" steerer.
If you can't find a stem you're best option is to find or make a shim with a 1/16" wall to reduce the ID of your fork to 1". Even then the stem selection will be limited since 1-1/8" steerers were introduced about the same time as threadless headsets, so 1" threadless and 1-1/8" threaded are both fairly rare (but not nearly as rare as what you have).
