We now run our campaign using Edition 7 Rules, with Character Sheets as generated by the Dholes House.
But here's the Edition 5/6 Character Sheet format we formerly used on the Mount Cthulhu campaign. It's generated using the Byakhee 3 program.
To create character sheets like this, simply unzip the content of the attached zip file into your Byakhee program folder, and then select the 1920 Mount Cthulhu character sheet.
There's more information in the enclosed Readme file.
Getting Byakhee
If you don't already have it, you can download the latest version of Byakhee (currently 3.03) from here:

Alternatively, you can still download a copy of the version I use:
