Hi Mica,
I've been hoping the card might have turned up on my bass.
Kenn, didn't know if you ever saw the thread on #76-449. I gotta' think this bass shared the workbench with your bass, and they seem to have much in common too. https://club.alembicguitars.com/series-i-basses-and-guitars/76-449/
Hopefully Mica turns up your build card along with the one to my bass... it's missing as well.
