I bought a used 1968 (i think) versalog 1460. This one doesn't have the date or serial number. From what i read online there was a short period of time in 1968 where a few were made that did not have the date on them but I don't see any that did not at least have the serial number (this one has neither). The name in the leather case is H.W. Jones and he must have lived in VA. That is where it was shipped from. It real nice looking and operates very smooth. So now if I really want to bore someone to death I can whip out the versalog and show them some calculations. LOL

The unbranded wood c.1941 Charvoz-Roos lives near my right hand.
The alloy Pickett found in garage sale, $5, stays in the case.
I know what to do with C D and a B or K scale; lived on them until 1972. I can get around a S or T scale. No use for the rest of that.

My dad was an elctronics engineer for what used to be called Dynalectron on the white sands missle range. He was still using his slide rule up to about 1970 then he was all excited about the new Texas Instrument Calculators. I was only 11 yrs old then and talking about math made my eyes glaze over. Now i wish i had paid more attention.
this one doesnt have the B scale or an A scale. It does have the K scale and lots of Log scales, and the C D scales. Also R1 and R2. I have been watching some videos trying to learn how to use it since it didn't have the manual. It will take me awhile to get used to having to place the decimal point.
I always wondered why my dad would tell me that I need to have a resonable answer in my head before I started the math problem.....now I see why he said that.

That's for a lesser model but they are all the same up to a point and I think that goes far beyond what you will use.

Thanks!

Crap. That's the thing about reading such topics. Now, I've got to dig around and find mine. When I came home from the Army, and went back to school with my slide rule on my side, both the math and the electronics instructors told me to go buy a scientific calculator. Or, fall behind the rest of the class.
I'm fairly sure that I can put my hands on that one. I have another killer nice one that I found in an antiques mall. Thanks for starting this post. I need new distractions to keep my brain active.

here is a 1944 video with some simple fun stuff with the C and D scale to learn or "brush up on" if its been awhile.

another video on how to keep track of where the decimal point goes if your doing a long calculation.

I really need to talk to my Dad when I get home next time, I ran into his old slide rule he used in school (He is a retired Civil Engineer). I'd love to find it and see it again. I'm a nerd descendant of a nerd :) He did punch cards for his masters degree, and used to spend hours 'validating' a new calculator he had by manually doing complex math and using his slide rule and confirming the calculator matched the results. lol.
