Weaver base for a McCann mount?

[altos]

Does anyone happen to know of a one piece Weaver or Weaver style base for a McCann mount? Or one with an open base that could be drilled to fit?

Thank you !!

Also, a Weaver one-piece 63B base for the Marlin lever-guns is flat on the bottom and should work.
You can probably find one of those locally to look at.
