non-BIP39 seed phrase, no idea what wallet - advice needed

Hi,

after about 10 years I rediscovered a seed phrase I had written down, unfortunately without any hint to which currency or what kind of wallet.
Metamask doesnt accept it, electrum doesnt accept it.
After a bit of digging (and re-learning) I found out that it looks like it has some different words apart from the BIP39 words, "bagpipe" for example.

Is there any way for me to find out to which kind of wallet the phrase belonged to?
If not, oh well. It could not have hold much anyways.
If yes, nice, very small bonus :D

Thanks in advance to anyone who could help!
