Are these really what the description says or did I get ripped off? :o

I don't see the logo on the right very often and was curious about it.
The tubes do sound pretty darn good.

I have had Mullards with the logo on the right on them. What you REALLY want to do is check the etch codes on the tubes near the base. They should read something like B 9 x B=Blackburn England 9 = 1959 and the lastr digit would be the month. Heres a link to help with etch codes

Description looks to be accurate, all visible details check out perfectly. However, that seller's attained notice before. Plenty of longplate Mullards in late '50s "Voice Of Music" gear, also other good stuff. At one brief point VM was said to be the highest volume music electronics retailer in this country. I can see the "B" code on the one on the left through from the other side, BTW. I like that type and vintage, myself. Those have clearly had some use, doesn't mean they can't sound good, hope they do and are working well. Type code if visible should be "f91" on each of those, possibly "f92" which was on a few of the last ones with dual rods holding the halo.
