Is this "Stewards" you mention a successor to J.H. Steward? I thought the family closed that firm down finally in the 1970s?

From an earlier post :

James Henry Steward established J H Steward Ltd in 1852. With his first opticians practice located on The Strand, he gained a reputation as a skilled manufacturer of optical, scientific, and nautical instruments. Steward quickly became the primary optician to the Government, the National Rifle Association, and the National Artillery Association. The business remained in the family until 1972 when the founder’s great grandson finally decided to pass on the mantle.

A long-standing employee approached his niece, Elizabeth Goldsmith and her husband Simon, who then took over both the business and a century-old commitment to helping shooters reach their full potential.

J.H. STEWARD (BISLEY) RENAMED
Today we continue to attend National Rifle Association meetings and hold a permanent trading location with eye testing facilities at Bisley Shooting Ground, Brookwood (home to the NRA). See our calendar of shooting meets here. J.H. Steward (Bisley) Ltd now serves shooters from around the world under the new name of JHS Eyewear.

This would have been the niece of the great-grandson then?

No - the niece of the long standing employee.

I stood in Simon's old opticians shop in Keynsham Bristol holding an AR15 and pointing it at the windows of what I believe were retirement flats across the road.
"better or worse", "better or worse", it was difficult to answer Simon as I was too busy looking for a patrolling policeman to walk by at that moment, on the other hand none of his customers being dealt in the shop gave me a second glance!
