David Schiller included a Heckel's Hair Tonic on his list of hair preparation bottles. I don't think it was this one though. The one pictured was probably a fairly rare advertising bottle. This was the same bottle as the UNO Tonic bottle sold be Fred Dolle.
The Heckel Brothers (Louis and John) had a Barber Supply business in Kansas City for about 50 years, starting in 1886.
