Crosman 150

[Jonah]

Got my "new" Crosman 150, 1st variant with twist power adjustment, yesterday bought on e-bay. Normally expect to have to reseal the vintage guns bought that way. To my surprise, no CO2 leaks. Can't find a lot of information on the twist adjustable power models since Crosman replaced the adjustment hammer if someone sent the 150's information repair. Even the old manuals I can find on the internet don't cover this model.



If anyone has a copy of the original manual covering the twist adjustment and could make me a copy, I'd appreciate it very much.

Sorry can’t help with the manual and I don’t personally know a lot about these either. Just wanted to comment. Looks like a nice example of these old classics.
I think I might have had that same one on my watch list too but choose not to bid on it because I just picked up a Crosman MKI a few weeks ago and 600 this last week. I’m kind of holding out for a Ted Williams version of the 150 anyhow. I kind of like the look of that model with vented rib.
These old classics sure are fun. Hope you enjoy yours

there are manuals and parts diagrams on the Crosman site

The manuals on the Crosman do not cover the twist power adjustment I guess because Crosman did away with the adjuster on any gun returned for repair.

That was my 1st pellet pistol. I have two of them now to relive my childhood. Pretty easy to reseal and both of mine will hold gas for several months after I resealed them

Where is the twist power adjuster? Does your 150 have the 2 power level rear cocking striker as well?

 

[Jonah]

It is the cocking knob like on all the variants, but can be turned to adjust power.

[SteveV]

So you had two power levels, and hammer spring adjustment, via the rear cocker??

 

[Jonah]

No, only variable power with this model. The two power levels are on the guns without the twist adjustment. Hope that is clearer. 

 

[SteveV]

That is clearer, thank you -

Never knew that about the 150, thanks for the education!

 

[Jonah]

Took the twist power adjuster apart today trying to determine what made it tick. Still don't know. However, pistol stays at high power which is where I would set it anyway. Picture of the disassembled twist power adjuster.

Top to bottom: hammer spring rod, hammer, end cap, spring, end cap, washer, tube rear plug, nut, lock washer, cocking knob. Now you know as much as I do, which isn't much.

 

[SteveV]

Lots of parts for sure, wow

Hey guys, I just purchased a Ted Williams and it has 3 power levels. Not much info on the web about them.

Do you know what size orings are used to reseal the 150 / 157 (and 2240 / 2250 / 2260), as well as the 111 / 112?

Used to have this info in an old computer that died.

 

[Diamondback]

Nice find!

Some good reading for you with info about the 150:

This article explains how the rotating power adjuster worked:

If you find this useful, please give me an Accuracy point. I seem to be missing a few? lol

 

[P_Bachman]

Helpful information- I don't have a 150 but I picked up a Mark 1 Target for cheap. Needs a piercing pin seal at the least, but mechanically otherwise seems fine.

Hi Diamondback

Did you manage to find the O ring sizes? as per your question. I inherited a model 150 from my father in law a couple of years ago when he passed away, sadly it appears the seals are gone and need replacing. impossible to find spares here and trying to order from the US is painful "sorry we dont ship internationally.""


would be great if i could find them in an imperial o Ring kit locally available.



Thanks

Rick
