Thanks for the comments. Keeping it readable is tough. I'm thinking about trying something with multiple sliders to increase the resolution. I'd rather not...
I've been watching eBay listings for a while, and I noticed that nearly every Aristo 870 that comes up for sale is in South America. I haven't noticed this for...
Hi Stefan, I can't answer your first question, but on the second question, out of the six full-size Hemmi made rules in my collection, every one of them has...
Just a reminder that all-plastic SRs and most later laminates on woodens were *not* celluloid, but usually some kind of PVC or Polystyrol. They are very...
Hi All; In reply to Stefan's question about German rules in South America starts at the end of World War II. Many German Scientists, Engineers and Technicians...
A very interesting story, although I doubt that this is the reason for the many Aristos in South America! Even though there were quite a few Germans who moved...
HI- I would think that the best lubricant for a plastic slide rule would be no lubricant at all. Unless the grooves of the slide are beat up, any binding is...
The CD sliderule catalog compiler by Herman van Herwijnen is no longer working on my new PC. I do not know why, but the main program exits with some cryptic...
I just find a slide rulers to calculate fly conditions, anyone knows if there are more of this kind of slide rules? I want to know if have any special value...
There are two answers to Andrew's question. In the first place, the Dutch Circle has done work over the past few years to make Herman's SR Catalogue more...
Sergio, what do you mean by "flight conditions"? I don't think you mean general purpose flight computers like the E6B since these are widely known and appear...

You better believe the manufacturers when they recommend that you keep plastic slide rules lubed! I have years of experience with them, and I have never seen...

Thanks Stefan, I had been wondering about the use of CR type rules ( of which I don't yet have an example). Having gathered a number of rules beyond my own...

I would like to find out if their is any uniform crieria for rating slide rules. From shopping for slide rules on Ebay I have found the following listed...
In my opinion, any such criteria are less than useful. I would rather see descriptions like "Excellent condition although this sliding thing is missing" or...
John: As you have sadly discovered the 9-10 of one person is the 6-7 of another. In an effort to put the evaluation of quality on a more even scale there are...

Hello All, I came across this list from the Dutch Circle of Sliderule Collectors that has both the rating and an approximate factor to use in pricing. It is...
I recently acquired a book of airline poster art, "The Art of the Airways" by Geza Szurovy. Toward the end, on page 175, there is a Delta Air Lines poster...
Without standard prices, it all seems pointless to me. I don't trust anyone else's assessment of condition anyway. If I can't see it, I don't buy it....
