Default Wanted, Plastic BT coupler for BT-56

I am looking for a plastic BT coupler for BT-56, for an Estes Goliath clone. The coupler has a ridge that separates the two tubes, and a plastic plus in it to attach a shock cord. I got the decals in a decal batch years ago and the fin can in a parts lot recently, so the coupler is all that’s left. The coupler has been used in other BT-56 kits in the past such as Mach-12 2130, Amazon 1469, Helicat 1465, Customizer 1500, and a similar part in the Omloid 2078. Picture attached, please let me know if I can buy one from you.

I may have one - can you give me the body tube dimensions so I can check it? All I know is it's an oddball size - similar to BT55 - that doesn't fit anything...
If it's correct - you can have it just for shipping.

Thanks, the bt-56 is the same as centuri st-13 tube. It's a hair bigger than bt-55 the info I have is an Id of 1.30" and an od of 1.34".

I don't know if it will work but I have a "mystery coupler". It's plastic, it has the ridge on the OD, but it does not have the "cross" on the inside. It measures 1.315" OD on the inserts and 1.368" OD on the ridge. It also has a molded eyelet on the ridge that can be cut off.

If you want it, it's yours.

Thank you so much for looking but that seems too big, I wonder what that could be for? I can’t think of a coupler like that from another company.

Sorry, I dug it out and it's smaller than that so it's back into my overflowing junk parts box.

5x7,

You wouldn't happen to be looking for *this,* would you?

(I bought this Mega Maxx starter set for the BT-56 tube to clone a Centuri Taurus back in the day [sometime in the last 20 years].)

I am also interested if you built the Spitfire SSI. The livery needs work but the design is neat and the nosecone with the canards was only used in two other rockets I think. I got one in the parts purchase but have never seen a good picture of one built.
