An interesting Danish flute

 

 
We had some difficulty in identifying the flute below, or even suggesting a country of origin.  There is some lettering visible on it, but not clear enough to make an identification.  There is however a maker's mark:
Four 6-pointed stars appear on the upper body, two on the lower body and one on the foot, just below the Eb key plate.  As can be seen, stars may not be the best description.  Perhaps asterisks or snowflakes?  Note also the somewhat irregular spacing.

The breakthrough came when European professional flute player, Georges Barthel, contacted me to say he had one rather like it, and, although the maker's mark was worn, he was able to make out the name Larshof.  Bravo, Georges!
 


Larshof

So, who was Larshof?  As usual, we turn to the flutemaker's bible, The New Langwill Index.  Interestingly, we don't find a Larshof, but we do find an entry for Jacob Georg Larshoff.  Even more interestingly, we find his mark was:

*
Larshof

*

Presumably, his real name was as the marks indicate, and the NLI tossed in an extra "F".  Unless perhaps the directories of the time listed him as Larshoff.

The NLI goes on to tell us that he was born in Wolgast in Swedish Pomerania circa 1760, and flourished as a flutemaker in Copenhagen in Denmark between 1798 and 1834.  He gained Danish citizenship in 1810, when he was appointed as Court instrument maker.  He exhibited a contrabassoon in 1813, and a patent for a new clarinet key-mechanism in 1821.  He died in Copenhagen on 1 February 1846, succeeded by his nephew Johan Dajon Rudolph.
 


About the flute

The flute itself is ebony, with ivory mounts, brass tuning slide and nine silver keys.   

Note the G# key is mounted below the break between the left and right hand sections. 

Note also the additional key on the upper section, probably a D trill.  This key is strangely placed - equally inconvenient to thumb and first-finger, so perhaps intended to be operated by either?
Note also the c key is mounted on the same block as the Bb key, making for an unusual balance point.
Perhaps the most intriguing feature relates to how the leather pads are secured to the key-plates.  As you can see on the left, they are sewn!  Presumably fine adjustment of pad seating was achieved by bending the thin metal of the shaft.

The embouchure

The "Early TV-shaped" embouchure hole is an interesting and conspicuous feature.  It's about 9.55mm wide from left to right, narrowing to around 9 near the corners.  From front to back, it's about 9.2mm, narrowing to around 8.4mm near the corners.  The corners are rounded a little.

Left undercutting is about 1.1mm, right 2.1mm, front and back around 1 mm.  The walls are not quite straight, but suggest a primary and secondary taper, particularly on the sides.  The metal slide is cut well further back on all but the left (stopper) edge.

Finger holes

The finger holes are interesting too.  Undercutting is hardly the word - these holes have been undergouged!  The undercutting along the length of the flute is normal if extensive, but across the flute, they have been scooped out vigorously, leaving a concavity on each side.

Tuning

As you can see, it's not currently playable, so tuning is a bit of a guess.  We can expect it to perform best somewhere around 425Hz.  Georges advises that his similar instrument works well at 430Hz.
