Type | ? Generic name (e.g. Enhanced Mannheim) or function/use for special models (e.g. Meteorology). If not the “standard” 25cm linear length proceeded by the form (e.g. Demonstration, Desktop, Pocket, Waistcoat, Lilliput or Book) + suffix when needed to distinguish between different versions (e.g. early or late). | Rietz |
---|---|---|
Sort | ? L/C/D/T/W/X where L=Linear, C=circular, D=Drum, T=tubular, W=watch, X=miscellaneous (i.e. the rest) | L |
Construction | ? Basic construction form of the body i.e. Closed/solid frame or Open frame or Duplex or Other | Closed/solid frame |
Material | ? Basic description: ivory/bone/wood/bakelite/plastic/metal/cardboard or combinations e.g. wood/veneered, wood/painted, etc | plastic |
Length | ? Mostly length in cm or ” (inches) of the D scale but excluding any scale extensions. But for circular or watch slide rules it is the diameter & for tubular or drum slide rules it is the overall linear scale length. For other mechanical aids it is the physical length. | 25cm |
Scales front | ? Standard (not maker’s) symbols for scales on front face e.g. A = X² (1-100) but § = generic symbol (signum sectiōnis) for any non-standard scale + scales between solidi / / are on the slide(s) whereas scales after vertical line | or after reversed solidus \ are on a straight or bevelled top or bottom side edge | cm \ K,A / B,CI,C / D,L | 1:25 |
Scales back | ? Standard (not maker’s) symbols for scales on back face e.g. S = sine (5° to 90° & 85° to 0°) or sin(x) but § = generic symbol (signum sectiōnis) for any non-standard scale + scales between solidi / / are on the back of slide(s) but scales listed after / / - notation are on another surface e.g. back of stock or inside a lid | / S,ST,T / |
Cursor type | ? Basic description (incl. material) + no. of hairlines, etc on any cursor(s) or alternative to a cursor - e.g. a stylus | plastic - 1 hairline + 4 peripheral hairlines |
Condition | ? Cn where n = 0-6 based on Herman van Herwijnen’s condition/quality scale | C3 |
Date | ? YYYY for year(s) of production or an approximation/range of years | 1971 |
Extras | ? Basic description of any accessories - e.g. case or stand + where relevant, an accreditation for image, etc | hard hinged green & clear plastic box |
Instructions | ? Details like “on back of rule” and/or language of instruction sheet/booklet - generic or instructions for common layouts usually not listed | German |
Comments | ? Any special or noteworthy traits + significant use-related facts + pertinent details of scales/tables in well of stock + any significant tables, etc on the back of the stock | |
In-Out | ? MM-YYYY / MM-YYYY of the date added/left the collection or <YYYY if exact MM-YYYY no longer known | <2005/ |
