Comparison to vintage 1389 tube/etc
-This tube is identical to the tube on my circa 1996 1389 Backpacker...except...my Backpacker tube does not have the 1&#34; (or so) opening for the hammer pin.  The front breech screw location/theads/etc are exactly the same.<br /><br />-The plastic piston, pump linkage, pivot/handle/clevis pins are exactly the same parts.<br /><br />-The barrel band is not tall enough for use with my Backpacker breech (the swing-out type loader with the bung for the pellet) and holds the muzzle end of the barrel pointing downward...well over 1/8&#34; drop from breech end of barell to muzzle end (14&#34; barrel).<br /><br />-The pump cup is slightly different on this newer model.  My Backpacker pump cup has a small dimple in the center that &#34;seats&#34; into the intake port of the valve.  This new pump cup does not have the dimple.<br /><br />-The valve is aluminum of course, my Backpacker being brass.  Of note about this new valve from AllianceHobby...this is the US version, it does not have the relief hole in the back end of the valve.<br />That said, web resources will tell you the difference between vintage and current valves.  ie: no dimple on pump cup works well, I hope, with the 1/32&#34; taken off the tip of this current-production valve-cone.<br /><br />-Yes, the hammer assembly is included.  However, I may attempt to continue using the rear-cocker system from my Backpacker, which fits the tube perfectly.<br /><br />-Thank you AllianceHobby for having this available.
