Pump tube bore/stroke for various Crosmans?

[flaircraft]

Is there any list or spreadsheet available that compares specs for Crosman guns?  I'm specifically interested in pump bore and stroke for the various MSP's, but it wouldn't have to be limited to that.  I figure there ought to be a compatability (compare and contrast?) guide or similar available for these lego guns...

If there's nothing available, how about starting our own list?  Something like:

GUN FAMILY     POWER SOURCE    TUBE ID              PUMP STROKE    VALVE VOLUME
13xx                MSP                      5/8 inch                   3.5 inch              1.5cc

2100/2200/       MSP                      5/8 inch                    5 inch                ??
LGY1000     

22xx                CO2                     3/4 inch                       N/A                 1.4cc


MK-177             MSP                     3/4 inch                      4.2 inch             ??


M4-177             MSP                     5/8 inch                      4.2 inch              ??


392/397            MSP                     3/4 inch                        ??                    4.2cc

DISCO               PCP                      3/4 inch                        N/A                  ??

MROD                PCP


etc.


If anybody has additional platforms that could be added or info to fill in the blanks, lemme know and I will add them to the above (or maybe come up with a better method, this is kind of a trial run...)  maybe there could be a column for pump swept volume too...

The 2100/2200 valve volume is 1.0 cc....
For the 13XX valve, they have 2 different length check valves.... I have 1.5 cc for the short check, and 1.2 cc for the long check....
A Disco valve is 2.5 cc not including the volume between it and the gauge block, which adds another 0.6 cc, making the air available downstream of the gauge block (which has a 1/8" hole through it) 3.1 cc.... If you drill out the gauge block, or fit one from a PRod, the "effective" valve volume (air available for the shot) then becomes 135 cc....
The Crosman 140/1400 pump is a 0.620" bore with a 7" stroke (twice that of the 13XX)…. All 13XX/2100/140 tubes are this ID....
The 39X pump stroke is 7.6".... and the bore is 0.777"....
The MRod tube ID is 1.06".... I don't know the valve volume....
The 22XX/Disco/PRod/Maximus tubes are 0.745" ID....

My Millennium Pumper used a Disco tube and 39X pump.... The extended Disco valve in the .25 carbine started out at 6.7 cc, then I added a 16 gr. CO2 cartridge for a total of 27 cc.... The .25 cal rifle version used a 2-piece valve with a volume of 28.5 cc.... Tube was 0.745" ID, stroke was 7.6"....

In all cases, pump swept volume is (D x D x PI/4) x S....

Many thanks Bob!  I'll add that info to the list.

Updated list:  (I looked but couldn't find how to edit my first post, so I'll repost this info for now)
