Hi Hat: WFL Speed King. Any idea what this is from?So does it look like the original set was a base, snare, maybe Hi Hat, followed by a floor tom and then a Club Date 13" Tom.Jim
1121 Hi-Hat would be from roughly 1963 or before. It was replaced by the Spur-lock model 1123 around mid/late 1963 although surely some of the older models were still available for sale in music stores for at least a couple of years following the transition.
Your order of acquisition pre-supposes that all the drums were purchased new which wasn't necessarily the case. That could explain the Club Date too if the owner happened onto a good deal on a drum that was either slightly used or perhaps had languished in a store's stock for a while. WMP was a very popular wrap at the time (almost the standard wrap for drums) and finding used or new single examples in music stores wouldn't have been difficult.
Really no way of ever knowing but it does look to be a set that was put together in the period and not a recently pieced together set (although, again, no way of truly knowing the exact history unless you have first hand knowledge).
Electronic drums are fun to play, they sound perfect in headphones and don't disturb the family or neighbors. I have a couple of sets and while they are fun they do not replace the real thing in the situations I need drums for. If I were you with a cool vintage set like that I'd try to find a decent used electronic set that I could afford ( you don't really need top of the line Rolands to jam in the basement) without selling these drums...because, if playing the electronic set rekindles your interest in drumming to the degree that you may get serious about it again, you'll deeply regret having sold such a cool vintage set.
