So far, all I have found is Tri-Angle Precision; however, their minimum is 10 each. Still looking for a supplier on the Internet. Please tell me if you find one. I usually use PayPal too.
Now understand that the RH spiral is more precise than straight.

Wow! Finding the appropriate .125" 'long' hand reamer is not panning out for me so far...
Anyone have a clue?

I am wondering what you guys hope to acheive by reaming the bushings? I understand the idea: make the hole slightly larger with a better finish...... BUT i doubt you will be able to make a straight cut without making the hole oversize or elongated. Really you need to have a drill press or a bridgeport mill to clamp the endbell, and indicate the hole on centerline before running the reamer through there. I definetly wouldn't run the reamer through the can to do the bushings.
A better bet would be to HONE the bushings. One advantage to honing is the cross hatch pattern that is left after honing helps retain oil lubrication, whereas a reamed hole will not be a lubricative. But honing oil STINKS!!!

I personally would NOT ream my Bushings. Once they are properly seated and broken in, polishing is all that's needed.

And Big Jim Greenemeyer agrees with you on this point; so, I am only going to polish them using a q-tip on a drill and polishing compound.
Many thanks for your insight.
