According to an internet search :-
Snail brand spanners were made by Thomas Smith & Sons of Saltley Ltd., Birmingham. Thomas Smith is said to have chosen the snail as his brand because his motto was, "The snail may be slow, but he gets there in the end".
Not forgetting "Footprint" and, at the heavier end of the scale, Alldays and Onions.
Re Golden Goose. I had 5/8 capacity chuck of that brand on an R8 taper supplied with an unmentionable square column mill. Figured with name like that it wouldn't be much good and took year or three before using it in anger. To my surprise it was actually very good. Kept it when the mill went as it was the only 5/8" one I had. Not a daily driver but certainly not disgraced by the Albrecht ones I normally use on the Bridgeport.
I always felt Abingdon King Dick and Snail spanners were somewhat on the chunky and cumbersome side. But the AKD version of the common American Crescent shifting spanner is better than the original although given the choice I prefer the Snail brand style having parallel jaws with the moving one driven up a straight shaft. Needs a bit more space than crescent tho'. Wonder how many brands of those there were? I have 4 all different.
