What is this?

Hey All, I contacted and met a guy and I bought a pile of rockets and parts from a Facebook Local Marketplace. When I saw the pic I thought that this was possibly a Vashon aluminum engine case but no. The handle has the Estes logo and and looks to have a cold power fill-up spot and some kind of spring loaded mechanism for launch? Anyone, what do I have here? This and the Estes GoonyBird Sky Shriek is what caught my attention

Its not an Estes Cold Power motor?

Looks like a Coldpower motor, release and can adaptor. Nice find. Very nice find.

These are my pics I didn't know what it was exactly. Like I said From the pics on the FB page I thought it was a Vashon but once I got it home I saw the Estes Logo on the trigger. Is it obsolete and just a collectors item? or is it still useable? or is the Ozone ruined for life with this? I have no idea how this thing works was mostly interested in the original Goony Sky Shriek

Some of us are very interested in Coldpower, see here from my previous incarnation:

Dr Zooch was a fan. He built a Mk II for Coldpower and Vashon testing. Propellant alternatives are available. I think it's time for a Coldpower comeback.

Or, alternatively, just send it to me and I'll cover the postage.

With that you could clone a KL-3 Marauder:

I have read that some enthusiasts have used canned Propel as a replacement for Freon.

what's you're previous incarnation? I wasn't born yesterday and have launched rockets since '73 But never "cold power" What happened to you? Bailed and then rejoined in '19? Just a little attitude.

Wow, cool! I love those things... kinda biased because I had a Vashon Valkyrie before I got any Estes rockets. CA fire regulations... anybody could fly them anywhere, so I used to throw it in my bookbag and ride my bike to the nearest schoolyard to fly it.

Estes had 3 or 4 different models of cold powered cars called " Land Rockets "

Rocketeer in my early teens. Bar in my 50's. Now in my 60's I've sold all my vintage kits to fund a rocket business here in Oz. Crazy I know. Coldpower would be great here where we have fire bans from October to April.

My collection of cold power. All have launchers and R-100 propellant in them. I will be at NARCON and NSL if you would be interested in seeing them.

Now -that- is a way cool collection.

Thank you.
The plain brown box peeking behind the Vashon Valkyrie is an early package version. Just has ink stamp on ends.
