I live in the USA. I sold my 1950-B monitor on eBay to a Canadian user that runs the bowling ally there. He told me that they needed one to replace another 1950-B that stopped working. Why would he (or I) fib about such things? -- I don't have images, but you can make a phone call to that bowling ally to inquire for yourself whether Amiga computers are still used for their scoring system. But when you ask them for images as proof, they may hang up on you.
Why would he be in the hunt for another 1950 monitor to replace the old one? Any VGA monitor will work on the 3000!
