A variety of small hammerless (concealed hammer) double-action-only revolvers with manual safety levers on the left side of frame. Most common configuration for TAC is probably top-break in 6mm with an 8- to 10-round capacity and a fixed triggerguard (contrasting to most velo-dog revolvers which typically had folding triggers.) TAC model markings included Velomith and Velo Smith among others, usually with intertwined TA logo hard rubber grips.
