Bonklip's & similar were popular choices particularly for military personnel during the 1930-40's, as the straps were quickly adjustable to fit all size wrists, importantly over flying suits.
Dudley Russel Howitt applied for British patent of his design on the 6th March, 1930.
However, a Walter Krement had applied for a similar design patent in America on 10th April 1929.
Later Zenette (English) also started to manufacture this type.
Howitt's design (which was the most popular) was manufactured for over 40 years by B.H. Britton, Birmingham (Vyse Street).
I have acquired some of these over the years but fell uncomfortable wearing them.
Anybody else have views, pic's of this memorable type of strap ?
Here's a couple of mine:
17mm Bonklip, gold filled.
16.5mm Zenette, stainless steel.
This one I do wear occasionally on a late 1930's Astor.
No name 17mm gold filled.
