| 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. | Novo-Mentor |
|---|---|---|
| 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. | A,DF / CF,CIF,CI,C / D,K |
| 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). | L,T1,T2 / CF,CIF,S',C / D,S,ST,P |
| 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 + 3 peripheral hairlines |
| Condition | ? Cn where n = 0-6 based on Herman van Herwijnen’s condition/quality scale | C2 |
| Date | ? YYYY for year(s) of production or an approximation/range of years | 1972 |
| Extras | ? Basic description of any accessories - e.g. case or stand + where relevant, an accreditation for image, etc | original box + grey plastic case + instructions |
