Saving Old Seagulls

I know ths is a really really long shot.

Has anyone got a cowling for the early Yamaha 2a they are willing to sell?

I believe they are white with a flip up cover over the flywheel.

I have researched and the Mercury's Mariner 2m is the same engine and cowling.

Looks like this,
