I already have one Sylvania GB-6189 with prefect label, now I get a old tube which look like the GB-6189 except it only with GB burn mark and nothing else, both tubes have same gray plate, square getter triple mica and support steel wire, the only different is their leg wire connection is opposite (like mirror image), is that a GB-6189 or a GB-5751??
