Kolb Baby Hammerless Revolvers

The Kolb company of Philadelphia, PA set up business in 1892 specializing in the manufacture of small .22 solid-frame revolvers with concealed hammers and folding triggers. Kolb revolvers were collectively known under the trade name of 'Baby Hammerless', they were five-shot .22 Short RF, revolvers with ribbed barrel and a frame latch that used two knurled buttons similar to the system used on contemporary Iver Johnson revolvers. Early Kolb revolvers had a knurled axis pin beneath the barrel, with a vertical spring catch on the right of the frame, which allowed the pin to be withdrawn for removal of the cylinder. References tell me that Baby Hammerless revolvers were manufactured from about 1911 to the early 1920s. In 1930, Kolb became R. F. Sedgley & Co.
