Definitely a cool find.It's not walnut, but the dutch elm Crosman was using does tend to have some interesting grain to it.The Crosman stocks I have seen were generally of one of the red elm varieties. Dutch elm refers to the disease that devastated the species.

CPHP and gamo wadcutters
I have a second variant 180 that I can barely feel the first click, but it is there. With all my 180s and like guns, there is a wide variation between low and high power. But consistent velocity whether low or high. Does your 400 seem to shoot more consistent at full power? If you are getting 120 shots per fill, your velocity is likely only 400 fps or so, maybe less. I've always shot my 400 mostly at high power because it is pretty weak on low. 550-600+ on high, for 60 or so shots. I got my first 400 ten or twelve years ago and have shot it a lot. Favored RWS Mr. Ks for a long time, they probably shoot the best. Also shot a lot of H&N and Gamo wadcutters. Found that JSB 15.89 domes feed pretty well. Also, H&N 21 gr slugs. A few years ago, I laid in a supply of Webley Vermin Pells, a rebranded Crosman item. Excellent wadcutters, I don't see why Crosman discontinued them. They shoot nearly as well as the RWS.
In my experience, many of the early manually cocked Crosman's have the first click; the purpose being to hold the hammer off the valve stem.
The 2nd variant 180 and 400 have a hammer adjustment on the cocking knob. at 3 o'clock an 1/8" allen wrench can be inserted to adjust this. Turn it in too far and you lose the first click, . but gain maximum hammer striking force which increases velocity. I just went upstairs and clocked my Sears 400 using my PACT 4 MK2 with IR sensors at 6" to start Screen. At high power with a 5 shot string the 400 averaged at 65 F. 548.36 fps. at 120 ft. above Sea Level. At low power it averaged 479.04 fps. Roughly a 69 fps. variance. I pretty much use Crosman 14.3 Domes on ALL of my Crosmans...yes even the 600's with no feeding problems whatsoever. Make the extaction and feed in one continuous fluid motion...don't baby it! Great fun shooters!dave

Great fun shooters!daveWith my 400,the adjustment screw is backed out as much as possible without locking up the cocking knob and I loose that 1st click when the gun is charged with co2.My 180 just doesn't have that 1st click at all, and it's adjustment screw is backed all the way out as well.Curiously the '62 400 can't be cocked with the safety engaged while the '65 180 can be.
