[Hron Bowler]

First document is a 2015 brochure from Sirens Horns & Hooters in Brisbane, Australia. Sirens Horns & Hooters purchased the R.V.B company some two decades ago, and many of the original offerings are still made. This brochure details the '6320' series of pneumatic horns which have been manufactured since the late 1970's, and as early as the 1950's in their earlier design form.
