Type | ? Usually a generic name preceded by the form if not standard linear length - e.g. Pocket Enhanced Mannheim. For special models often supplemented by its function/use - e.g. meteorology. Sometimes a suffix is needed to distinguish between different versions - e.g. early or late. | Export Duplex |
---|---|---|
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 | Duplex |
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 | ? Mostly standardised (not maker’s) symbols for scales on front of stock e.g. A = X² (1-100) but § = generic symbol for any non-standard scale. Scales between solidi (/ /) are on the slide(s) whereas a vertical line ( | ) or reversed solidus ( \ ) + a symbol denotes scale(s) on a straight or bevelled edge. | K,T1,T2,DF / CF,CIF,CI,C / D,S,ST,P |
Scales back | ? Mostly standardised (not maker’s) symbols for scales on back of stock e.g. S = sine (5° to 90° & 85° to 0°) or sin(x) but § = generic symbol for any non-standard scale. Scales between solidi (/ /) are on the back of the slide(s). | LL03,LL02,LL01,A / B,L,CI,C / D,LL1,LL2,LL3 |
Cursor type | ? Basic description (incl. material) + no. of hairlines, etc on any cursor(s) or alternative to a cursor - e.g. a stylus | plastic duplex - 3 hairlines + 2 peripheral hairlines front + 2 peripheral hairlines back |
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 | 1974 |
Extras | ? Basic description of any accessories - e.g. case or stand + where relevant, an accreditation for image, etc | |
Instructions | ? Details like “on back of rule” and/or language of instruction sheet/booklet - generic or instructions for common layouts usually not listed | |
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 | Only model in the series = inexpensive school version of 2/83N |
In-Out | ? MM-YYYY / MM-YYYY of the date added/left the collection or <YYYY if exact MM-YYYY no longer known | 03/2014 |
