Cairns, From Hunt & Roskell, 105 High Street, Portsmouth.” Gilt brass security clasp. Fold out easel stand with ribbon restraints to verso.
Condition: All three instruments in very crisp original condition, the barometer working well, having been the subject of a detailed overhaul and calibration under laboratory conditions (see performance chart). The compass easily finds north, the locking mechanism securely arresting the card. Both instrument cases show signs of wear with minor marks only. The thermometer responding correctly to rise and fall of temperature.
The travel case the subject of some restoration, notably the lower edge of the right hand lid, the work conducted as the original construction both in form and materials. The leather exterior faded, worn and marked with evidence of moisture damage to the dyed finish, some losses at corners and evident damage to hinged section of right hand lid. The case structurally sound, the fabric interior with general wear and some fading though still with a good measure of vibrancy and colour density.
Comments: Compendia of this type are now rarely seen: the two major instruments are not only matched and original in all respects, but are beautifully decorated on the versos. It is not clear if this decoration is purely decorative or in fact a very elaborate monogram, but in any event this type of decoration is seldom seen and would at the time of purchase greatly added to the cost. Additionally the instruments are of the smaller size than standard, and occur very less frequently.
Joseph Gustavus Cairns is shown in the censuses of 1891 and 1911 as being a jeweller and watchmaker. Cairns would appear to have bought in this very handsome compendium from the highly respected London jewellers, Hunt & Roskell. Hunt & Roskell held a Royal Warrant from Queen Victoria.
In all, this is a highly desirable collector’s piece in much above average and very original condition.
