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! )
