Here is a set of nestling, handled tubes.  All the tubes are 3 5/8" long. The sizes inscribed on the tubes range from 15 up to 2.  Based on the 5/" size of the #12 tube, I guessed these tools may have been used to reload primers in reusable brass shotgun shell casings. If my conjecture is in error, please let me know ASAP.

Thanks guys!

If I remember correctly, there was a set like this on here a while ago. Believe they are used to cut plugs in (cork, or rubber?) for tubes to go through...for vials and the such?

That was it, Scottg identified it.

Yeah well kinda
A druggist's cork set for making up corks for bottles
  is what I heard.

Select a larger cork and cut it down for your Turlington's Balsam, or whatever.
Who could stock every size cork in the world? Much less brand new corks all the time.

   Unlike now, druggists didn't make all the money in the world once upon a time. Druggists were better thought of than doctors  (god forbid, I'd rather just to go the barber/surgeon!),
     but only barely.  Pretty slick and slippery on the whole,  druggists.
I tell ya,
  Man they better have a decent pickle barrel, and some good cigars in stock, you were going to go hang out in a drugstore!

Some of them worked hard their whole lives and made the world a better place before they were done. Much better, some of them.
But many just hawked the latest snake oil, by the bottle.   Or even worse.
 
   I happen to have a copy of the Druggist's Handy Book here. It tells how to make up many of the popular remedies and nostrums of the 1880's.
Running short of Dalby's Carminitive?  No problem. Go to the dump and bring back some empty Dalby's bottles.  Rinse them out. 
Now add this, and that, and stir and cook.
Waa-laa here is your medicine!

Anyway pick the size cork cutter closest to the bottle mouth, and run it down a bigger cork, and there is your stopper.
That'll  be one dollar please.

It all sounds good except ...............................
Nobody told me how you get the damn cork you just made out of the tube!!
You have to pull the pin and unscrew the cap and push it though? 
 
I guess
yours Scott

Now you need a sharpener to go with them.

Surgical hemorrhoid removal tool.

Thanks, gentlemen, for all your informative responses.  I was able to confirm the cork cutter ID supplied by Scott G for this tool in my Dictionary of American Tools.  The rest of the responses dealing with druggists, relative esteem levels accorded druggists and doctors, and hemorrhoids, were superfluous, but then time hangs heavy on idle hands.

Its a standard set of cork/stopper borers. When people actually still did wet chemistry these could be used to bore holes in stoppers to insert tubes. I got one at work now. Here is a link that shows them.

Eek!  $311 They don't give those away...

Anything from a scientific supply comapny these days is insane.
