I found this Morse Key Maker on the ZA/IK3RLM
website. They are as nice as any I've seen:

Here are just a few . He makes covers too. The logo
on top is reminiscent of the Mercury Paddle

On his site are pictures of his lab and tests he does. I could not
find a price but I guess if you have to ask...
