New and updated Mursten-era parts

[Willy Tschager]

No.
I don't understand Willy. I think it is correct to add the ribs in the subfile. They are different.
The main question here is the number on all the printed versions.

I simply don't think it is worth renaming all the existing patterns. Just go on from here for the missing patterns and add the ribs accordingly.

BTW. https://www.ldraw.org/parts/official-par...tid=925p03 has 3 ribs.
