Yes indeed, very fine job! That's truly "old school" service. I will say, there are still vac shops who attend to this level of detail, and one of them is Boulevard Vacuum here in Los Angeles - I've mentioned them many times in the past.
Boulevard Vac was started in 1949 and is still run by the original family; the founder's son Ron is now the owner. When they get in old machines like this, they lavish the same sort of care on them although it would be smarter, business wise, to convince the customer that her "dust-belching dirt-breeder" should be thrown out and replaced with a new plastic marvel (that will self-destruct in a month). They have loyal customers who have been coming in for decades for new purchases and service.
Quite a few times I've gotten calls from Ron, "Say, do you have a replacement switch for a Lux 30..." and so on. Always happy to help him when I can. One time a man had brought in a really nice Hoover 150 for service (don't know if he was the original owner or not). The bag needed replacing and he wanted an original replacement for it! Of course, he had to be told the disappointing news that such a bag had not been available for quite a few years, although Ron did call me "just in case," to see if I had one.
btw, great Electrolux boxes in the background! Do they contain the original machines? If I'm not mistaken, the one on the bottom is the 1949 XXX and the one on top is the turquoise G. I'd **LOVE** to have that G box!!
Again, a thousand accolades on your fine work!
