Pressure reducing valve ID

[precision80]

Can anyone ID the manufacturer, I need to repair it. Edit- maybe its Watts? If so anyone know the repair kit code?

Loosen the nuts, and rotate so the mfr is showing. duh
Also, I have so many wasted rebuilds that didn't work, we normally swap out if at all possible. Being LF (lead free) it isn't too old.
likely Zurn Wilkins but not quite from what I see.

There are no markings on the other side and I really didnt want to loosen those nuts, otherwise Id just replace it. Its only 2 years old but full of rust inside. I think its the Watts LFN55b

What is to the right? Is there a tag that has been painted over?
