Rapide air accessories

[Cheddar Bob]

Recently acquired a splat master rapide and I'm wondering if anyone has a quick change or constant air adapter they'd be willing to part with. Photos included for reference material.
thanks for looking, any help is appreciated

I have remote line adapters.... And maybe the comp style asa

Just as an aside those quick changers are very rare and equally as sketchy. I love using it but the only thing keeping the 12 gram as bay is thin plastic.
