Details of: Lawrence Engineering Services - 9-K
| Type | ? A generic name (e.g. Rietz) or function/use for specialist models (e.g. Meteorology) for grouping similar models across makers. If not “standard” 25cm linear length, preceded by the form (i.e. Demonstration, Desktop, Pocket, Waistcoat, Keyring, Lilliput or Book) + if needed, qualification to distinguish between versions (e.g. early or late). | Music Transposer |
|---|---|---|
| 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 | Wood/painted |
| Length | ? Mostly the linear length of the D scale (in cm or inches) excluding any extensions. For circular/watch slide rules the diameter but for helical/tubular/drum slide rules it is the overall scale length. For other calculating aids it is the physical length or LxWxH. | 8½" |
| 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 | § / §,§ / § |
| 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 | |
| Cursor type | ? Basic description (incl. material) + no. of hairlines, etc on any cursor(s) or alternative to a cursor - e.g. a stylus | none - not needed |
| Condition | ? Cn where n = 0-6 condition/quality scale where 0 = brand new in box & 6 = broken | C4 |
| Date | ? YYYY for year(s) of production or an approximation/range of years | 1947 |
| Extras | ? Basic description of any accessories - e.g. case or stand + where relevant, an accreditation for image, etc | Manila paper envelope |
| Instructions | ? Details like “on back of rule” and/or language of instruction sheet/booklet - generic or instructions for common layouts usually not listed | Printed on envelope |
| 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 | For constructing chords in any key & transposing one key to any other |
| In-Out | ? MM-YYYY / MM-YYYY of the date added/left the collection or <YYYY if exact MM-YYYY no longer known | <2009/ |
