This measure has an iron body and brass tube. There are eleven  interchangeable powder measures, three undrilled. The powder measure holes look like pistol charge quantities. All the bored measures have a stamped number and a handwritten number. The handwritten is probably someone's calibration for a particular powder.  I'm going to sell it for my friend but I don't know what to call it or what to ask for it. Suggestions on both?

I’ve owned several of those, and also a version Lyman used to make. The later versions by Pacific had a clear plastic hopper, btw.

Currently I’m relying on a very similar measure made by Bonanza, along with an RCBS Little Dandy.

I’ve seen them priced all over the place, starting about 25 bucks in rough condition with just one rotor, up to 80ish or so. The number of included rotors seems to increase the price a fair amount.

I’ve heard of fellows making additional rotors just as marlinguy suggested, out of brass or aluminum, as well as some sort of plastic, perhaps delrin?

They are, in a word, very handy. If you construct your own rotors you can make a foolproof powder drop that will give you an exact charge. 

I think this style fell out of favor because of the consistent repeatability of adjustable measures, but holy smokes they can be fast and convenient if you have the right rotor.

The Pacific Pistol Powder Measure had a long history dating from before WW II.  In fact, you’ll find some made during the war wit steel rotors.  They were also made for a while under the Bair name… I think the shop that became Bair may have made them under contract for Pacific.
So far I’ve seen mostly rotors with markings for Bullseye powder (just a number or BE), Unique powder (UNQ) and a very few for 2400 that were so marked.  Obviously they were designed for use with pistol loads or at least powder charges in that range.
Most came equipped with a clamp integral to the body casting so they could be affixed to the loading bench while the latest ones may be seen with a plate that is bolted to the bench to accept an extension moulded to the body of the measure.
Price can be all over the place, but I buy them only on the cheap.  I found a measure with 7 rotors (3 un drilled) on eBay this weekend and got it for $29 plus shipping.  Even though they are intended for pistol loads, the largest charges available can reach the lower end of our Schuetzen loadings.

On mine one can mount the measure easily so that one can move the case to the measure. Was designed to do so.

Easy to overcome. Just trying to help if you would like to use it at the range.

I'll see if I can dig my user measure out and take a picture of the data sheet. 

My new-to-me PPPM arrived today.  I think this makes #6 (or is it 7?) this is probably the nicest one I have of this vintage, complete with box and instructions.  It is old enough that it just lists 8 Bullseye charges, and I got 3 of the smallest ones.  The good news is, the seller didn’t notice that the rotor installed was a factory blank as well, so I ended up with a total of 4 of them out of the deal.  I’ll try to post a picture if I can.  There is some good info on the ARTCA Forum but it is currently down for an upgrade.  I can’t wait for it to return.

I did some digging and found a post I made on another forum a few years ago.  Here is a piece of that post, containing all the rotor data I had at the time;

“PISTOL POWDER MEASURE
* Standard among pistol reloaders who demand speed and accuracy. Visible powder tube.
* Equipped with fixed charge rotor in 2, 2.5, 2.7, 3, 3.2, 3.3, 3.5, 4, 4.5 or 5 grain bullseye, 6, 8,10 grains Unique, and 12, 14, 16 grain 2400. Blank rotors available.
* Wing - nut fastens measure securely to bench-mountedbase plate. Detaches easily for powder removal.
NPM-15 PACIFIC PISTOL POWDER MEASURE.... ... .... ... .. $13.90 
9-J18 EXTRA ROTOR..............$ 3.50

I also have acquired rotors for 5.5, 6.5, 7. and 7.5 gr of Unique, which aren't listed here. They seem to be factory, but markings vary widely.

Additionally they will be encountered with black or blue painted bodies, brass or clear plastic powder reservoirs, and either a cast on clamp or the cast on plate that engaged a plate that could be attached to bench or shelf.  The largest volume rotors reach the small end of volumes we use for Schuetzen.  Hope this will be useful to those of you who stumble across one of these old powder measures.
