I wonder if RUMA RIKA actually means "ruime rijke": wide and expensive/rich, or that it could be Dutch "roemrijk"/ German "ruhmreich": glorious, or in this context flamboyant, extravagant.

All earlier translations interpreted RUMA as wide. For two other OLB-fragments with "roemrijk" (ROMRIKA, ROMRIKSTA), see below. There are more words that have an U - O variety, but I don't have many examples yet (see below).

Other examples of U - O variety:

HVNDRED ca. 20x ~ HONDRED 4x

Between Dutch and German, the O/OE - U variety is very common:
Roem ~ Ruhm
Honderd ~ Hundert
Hond ~ Hund
Moed ~ Mut
Bloed ~ Blut
Som ~ Summe
Voet ~ Fuß
etc.
