Chris, thanks for the link. After studying the picture I believe only one set of barrels has an inscription (the farthest one).
There is another set here

In the main picture the 410 barrels are in the front with the splinter forend and has an inscription while the 28 ga barrels next to it does not appear to have one. Now I'm even more confused.
I used to have a repro DHE 28ga two barrel set but don't remember if both barrels had inscriptions.
