As an interesting aside, I had to leave the Bryman name on the label on my EEVblog units, otherwise it would have required a new UL approval process even though it's exactly the same thing. Some red tape thing.
Same for the model number, I couldn't change it, but they could offer me BM786 which was already part of the slew of approvals they got for the whole 78x series. You can see this on the PCB inside with all the model numbers listed. But they ended up not offering the 786 model to the market, so it was free for me to use.
With the 121GW that design was done from scratch with Kane, so I could have any model number I wanted.
I also have a new pocket meter coming from Sanwa, and that is completely EEVblog branded, but I think still has Sanwa moulded into the case on the back, and I renamed it the 1980s
I could do that because Sanwa do their own in house certification.
