A top of the line rule by any standard, and a real pleasure to use.įaber Castell 1/54 Darmstadt - July, 1961 Although I don't have the manual for this rule, I think the outstanding features of this model speak for themselves. I've also included links to scans of the appropriate catalog pages for this model rule, stored at Sphere Research Corp's Slide Rule Universe. Also included with the rule was a fairly typical single-sided plastic "cheat sheet" of common formulas and conversions, shown in first high resolution scan. The unmarked case is made of high quality leather with a dark brown finish similar to my Nestler rules, only much sturdier in this case (most Faber rules come in plastic clam-shell type display cases). You might want to compare this rule to the high end Aristo and Nestler offerings in my collection. Date code stamp appears to read 11/68, which is consistent with the late model feature set shown on the rule. It is also a "self-documenting" rule, as each scale has an example on the far right of what the scale represents and how to use it. Made of plastic with adjustable anodized aluminum end braces, it features a nine hairline cursor (5/4 duplex), and a whopping 24 multi-coloured scales with trademark green accent stripe on the primary scales and extensions at both ends of the major scales. Although not quite as advanced as the top of the line 2/83 Novo-Biplex series (what a name!), this rule is a close second and features almost all of the well-known Faber innovations. Many of their rules have survived very well to this day, and remain among the most sought after by collectors.įaber Castell 2/82 Duplex - November, 1968Īn example of one of Faber's late model high-end duplex rules, obtained in mint condition. Faber was also one of the more popular slide rule sellers here in Quebec, along with K&E and the Hughes Owens company.
Always the innovator, Faber was often copied but rarely duplicated by other manufacturers. Later rules were made out of Geroplast (their name for plastic) and featured some of the most useful and advanced features ever seen on slide rules. They sold a wide range of models, with many of their early offerings made of Swiss pearwood or boxwood with celluloid facings.
Faber rules are considered by many slide rule enthusiasts as among the best ever made. Eric's Faber Castell Slide Rules Faber Castell Slide Rulesįaber Castell rules were manufactured predominantly in Germany, and they were clearly the dominant European slide rule maker.
