Barnes tailstocks appear to differ a little in design from model to model. This example had a top which could be off set for taper turning, the bed clamp was at the side, secured with a single nut, whilst the No. 2 Morse taper barrel was clamped by closing up a slit in the casting.
The handwheel, though of a respectable diameter, was bereft of a handle, which would have made withdrawing a long drill a tedious experience.
