For this project of creating a glass case for a 1925 radio circuit, I think it looks just fine AND credible for a 1925 hobbyist craftsman.
Of course I need to get some proper round head-slotted screws. I'll get brass and nickel plate. I see that nickel plated brass screws have just about disapeared from the market in favor of stainless steel... But they just don't look quite right... (Too good! )
