August 22nd, 1899 letter from George Scherff to Nikola Tesla

New York, Aug. 22nd, 1899
46 & 48 E. Houston Str.

Nikola Tesla, Esq.,
Colorado Springs, Colo.

Dear Mr. Tesla:

The work of the shop continues on the shaft, brush-holders, armature, commutator and finishing of the castings of the third independent break and the development of the pump.

The speed of the second break, Mr. Uhlman says, is now up to 2100 revolutions per minute.

Respectfully,
Geo. Scherff
