• Model: Jewell Wavemeter Pattern No. 90 [Version 4] - Weston Electrical Instrument

• Shape
• Tablemodel, Box - most often with Lid (NOT slant panel).

• Notes
• This Wavemeter Pattern No. 90 from Jewell Electrical Instruments Co in Chicago has a range of 150 - 625 kc. It shows the result in kc and meters. It is very strange that there seem to exist at least three quite different versions of this Wavemeter with the very same name. This version is described by a seller as mahogany cased with brass plate mounted to front side "Jewell Wavemeter Pattern No.90 Range 150-625 Serial #335489 Jewell Electric Instrument Co.Chicago USA. Also on the inside, the top plate of mechanism is mkd."Hammarlund Mfg.Co.Inc.New York Bakelite Pat.Apld.For. Top is cast aluminium". We believe that the knob is not autentical.
