That's the nature of the beast for 99% of these sets. They came from the
factory with a front tag and internal modules that matched the
manufacturer's name. The first time the set went through maintenance which
involved swapping out a defective module, its pedigree was lost to the
ages. Defective modules would be removed to be repaired later, and either a
new or repaired module swapped into its place - whatever was on the shelf,
next in line. This is how it was explained to me by a former tech and I
think, the general understanding of many. For a while there was some
prestige attached by a handful of collector types to having a radio with
matching modules. In reality, a good functioning R-390A is just that -
regardless of the names and numbers on the module.

I think you'll find that to be a typical inspection stamp, which is why you
find it throughout the radio.
