Speed Passion GT2 LPF PCB markings

[Chesty]

If anybody has view of the bottom of a Speed Passion GT LPF speedo...

My recently purchased LPF has HW427BV2.1 stamped on the bottom of the PCB - can be seen through the clear plastic case.

Just wondered if others had the same marking on them?

I know they share Hobbywing internals, but is it meant to be as blatant/obvious as that

There is a very good reason for this, its not just out of interest
