SLD Part Needed

[Yarf]

Guys, absolute Hail Mary here but I recently obtained a SLD flare pistol in great condition EXCEPT it is missing the selector lever and one of the pins that restricts the rotation of that lever. Does anyone know of anywhere where I could find that part? I would be prepared to pay an absurd amount of money for that.

Alternatively, if someone has one of these and would be prepared to help, I can use a set of decent photos to build a 3D cad file and get one printed in aluminium.

Let me know, any leads appreciated.
Cheers, Geof
