Maybe -- but the Boss OU is an entirely different beast.
I always figured that Robertson saw the Lancaster OUs, saw the buzz they were creating, and figured he could do better.
This is what Google's AI OVERVIES says:
Disputed Origins (German vs. London): While branded as high-quality London guns, some evidence and testimonies suggested that the rough, unpolished actions (the "in-the-white" metal parts) for the Lancaster O/U boxlock ejector guns were imported from Germany, rather than being forged in London.
That's in line with what I thought.
