OWD,
I would advise you to look up the Tom C. Kidd article "An Expatriate Returns", in volume six, issue four, winter, 1995, and have a look at just how a well maintained and daily used gun should look after 80 years of service. The article deals with a Fox that spent about that amount of time on the grounds of an English shooting club, with skilled maintenance performed as needed.
The gun doesn't look like the HE pictured above, by the way, or, I gather, like a few in your collection. But, nobody could say it doesn't look great.
Best,
Ted
