Recently, I noticed two adaptations to the old boring requests for updates, renewals, etc of Ebay/PayPal acount/security, etc. First is receiving a notice at...
On The Slide Rule Trading Co website (http://home.att.net/~ross1/SRTC/Managing.htm ) Paul Ross says that the critical issue is whether the copier uses "CCD" or...
Steve, if you have some Faber-Castell SRs, you might want to take a look at their ST scales. On the few I have, and some that I have looked at on the web,...
Hi Marion, The only two FC rules I have are a 2/83N and a 8/10 circular. The 8/10 has no gauge marks on the ST (too short - it's the innermost circle), but...
Thanks, Alberto, nearly every scanner I have looked so far uses CCD sensors so that's not a problem. Some do not have the mechanical ability to manage thick...
Marion, Marion, They are correction marks in the range of 4-6 degrees. and will give the correct functional values for sine and tangent. Peace, Ray Johnson...
A good rule of thumb seems to be the thicker the scanner the better it's depth of field-most modern scanners seem to be getting thinner unfortunately. Try...
Hi Marion Re Scanners: Some three years ago I purchased the HP8200 because it had a larger scanning bed which enabled it to scan most 12 inch slide rules. It ...
hi all recently i bought 5 aristo 0968 and i was surprised that no one is perfect simialr to another but differentiate in something for example one has bronze...
The Aristo Studio was introduced in 1949 and lasted until they closed shop in 1977-78, so it is quite natural that there were some changes during that time. ...
Seriously! I believe I have a Bulgarian pocket rule <http://tinyurl.com/2wten4> , old in style (wood and varnished paper), low-end, but rather well made...
I cannot read Bulgarian but I have deciphered enough russian variable star tables to tell you that the second word under what looks like a brand name is means...
Tom, once again, many thanks for your excellent scans of an interesting rule! Despite my name, I have only a rough understanding of the Cyrillic alphabet, and...
Thanks to everyone who responded (including those who responded off list). Cyrillic Catt gets the award for best pun of the day (but that's a pretty low bar...
... Hi Cyril, I hate to argue with someone whose name is so closely tied to the script we're discussing :-), but I read those words as Vetoli / Smetachna /...
hi john many thanks for info yes you have the reason and i made a mistake in describe it the difference is in thickness and not width.. maybe in future i will...
John, As I read the e-mails from collectors I'm fascinated by one question which keeps popping into my head. Why did slide rules, particularly pocket rules, go...
Don't worry. Your English is better than my Spanish/Portugese/Chinese/Italian/(you name it). Besides, my English isn't that much gooder than yours. 8^) ... --...
Just a few comments... "Vetoli" is written in cyrillic italics, which is different from standard cyrillic! The last character, which looks like our 'u', is...
John, I'm in complete agreement with your thoughts. I carry my Jeppesen- Sanderson CR-2 circular slide rule for the exact same reasons you mentioned. Cheers, ...
... Hash: SHA1 ... Earl, It's been a tempting idea. I carry my old Post 1444K or Concise CTCS-552 sometimes, but I don't really like the risk of breaking or ...
Hi- What sort of information are you looking for? You will find the old flight calculator's on ebay fairly often, and for not very much money. Pickett made a...
Hi! I'm loocking for something more suitable to fly ultralight aircrafts. Not that hight and not that fast :) It would be great to find the planes to build one...
Hi Matteo: Sorry, I don't think you will get anything but a few dollars for those. They are simply too common. Might be better to keep them or use them as...
Earl: I think the answer is quite simple: demand for SRs dropped, like off a cliff, in the early 70s. Aristo tried to hang in there, with their most popular...
