I would really like to find one of these scopes. I was real close on a Hy-Score version. It was sweet except that some of the focuser parts were missing and I just couldn't see it was worth the asking price without those. Bomber Bob was kind enough to provide me with the parts I needed, but by then the woman selling the scope had decided not to sell it. The only thing I can think is that the scope must have some sentimental value to her. Here's a couple of pictures of the one that got away.

Too bad that one got away.  There aren't too many of those around.  The scope is a rebrand of the RAO T-6C.  The mount is very neat and works quite well.  Mine has a SN of 7237, very close to that one.  Like almost all RAO 50/500 scopes, it's a great performer.

I have serial number 7535 which is only 15 units lower than that 7550 number.

 

Inspection tag is dated 31.10.10 which is Oct 10th, 1956.

 

Ditto to everything that Charlie said.

Nice to have that dated inspection tag.

Nice scope! I'd like to find something like that.

 

For general cleaning of a tube I use whatever I have handy like Awesome, Simple Green, or Dawn. Lately I prefer Awesome as it seems to remove unknown marks and stains better than the others. I follow up using Turtle Wax. Also, Turtle Wax polishing compound is great for stubborn marks.

 

Nevr-Dull is my go to for chrome and aluminum, but only use the blue can brand. I once bought the Eagle One brand and it was terrible. Blue Magic is another good solution for chrome and aluminum that needs a bit more polishing.

 

I have a small prism from a Celestron/Carton diagonal (it looks like the same housing), that might fit if your prism doesn't clean up well.
