[Coco] vendors of empty cartridges shell for coco

[didier derny]

Is there any vendor of empty cartridge shell for coco ?

 

I now that such vendor exist for c64 cartridges 

But I've not been able to find one for coco.

 

I don't like the idea of vampirising existing product to recover

A cartridge shell.

 

Any idea ?

 

Thanks
