Mystery Coupler

A little while back, cavecentral sent me some Parts he was'nt using.(Thanks again cavecentral).
Included in the goodies were this Coupler and the Pre-Slotted Body Tube. The Tube is approximately 1 and 7/8" in Diameter.
Anybody know what it is from, or what can be built from it?
The Coupler has this weird Notch in it.

Could that be an interstage coupler? The notch could clear an engine hook, but the plastic wouldn't hold up to the staging gasses. Even with electronic ignition, you'd get one flight out of it.
Seems I've talked myself out of my own idea! Lol.

It's an Enigma, is'nt it???

I suppose I could just ask cavecentral, but that would take all the fun out of it.
It's better that we guess at its intended use until someone who knows tells us.

Isn't that how religions start? Someone will say it's a sign from god, since there is no obvious earthly reason for it, and boom, there goes our Sundays.

it is a transitional coupler for a rocket that can be flown as a single stage upper and lower or just the upper stage by itself. think Terrier Sandhawk...

Estes Terrier Sandhawk it is!!! Found the Instruction Sheet with a Diagram. https://plans.rocketshoppe.com/estes/est2083/est2083.pdf

I don't remember this rocket. About when was it available? It looks really cool. I want one.

The Instructions call for an E15, so I'm assuming some time in the 90s'.

Yes. It was part of their Pro Series.

I didn't know what it was or remember how I got it. Figured just a reducer or sorts.

Well thank you for it anyhow. I will likely try to find it a good Home with someone who has interest in building that Model.
The TLP Kits are coming along Nicely! You can see the Tan Sam Pics' in my Thread in MPR.
Thanks again Cavecentral.

You're quite welcome. I added a bunch of misc. parts since you said you like scratch building. No clue if you could use the smaller stuff or not.

I think even a Micro kit that I got free with an order of Q2G2s from Quest got sent for your disposal.

BTW - Nice job with the shark teeth!

Thanks. The Real TAN-SAM has the Shark Teeth, so I had to make the Decal. Making the Decal took a few days and was really fun.
That Micro Kit was the Fliskits Teeny Triskelion. I built it and just need to get some Motors to fly it.

I built 2 missiles so far. The Hellfire (All Black) and one that looks like the TAN SAM but has a pointy nose cone (Primed - not yet painted). Others will wait.

Hmm . . . Maybe I didn't get it from Quest then. I thought it was a freebie with some order.

It's not done with Paint yet, but it's getting there.

I've decided to go ahead and start finding/making the rest of the Parts so that I can have my own Terrier Sandhawk!

The Body Tubes are odd Sizes as far as I can tell, so I'll need to figure out which tubes to order that will work.
The Booster Tube I had was not really up to par with the type of tube I like to work with so I scrapped it.
Other than the Coupler, this will be mostly scratch built.

I'm glad you properly identified it. For awhile there I thought it might be some sort of Martian intrauterine device.
