I found no thread on the Colorsound Wow Swell, in the video below just referred to as Colorsound Wah. Nor is there a thread on the Solasound Wow Swell, which is, if I'm not mistaken, an earlier, internally different circuit with some deviations in the circuit.

Luckily AG traced the circuit, but from a pink unit?

I just had to grab these gutshots from Refurb.com, accompanying text says:
One of the rarest pedals out there - Wow! This original late 60s English made Sola Sound / Colorsound pedal has become legendary for its dual function of both Swell & Wah - featuring the original famed 2N5172, 2N2926 transistor wah circuit.
This early version was used for the recent Stu Castledine Colorsound reissue!
Good condition with slight markings to the pedals exterior. Please see the attached pics as they form part of the condition description.
Worldwide shipping! Please let me know if you have any questions.
So maybe the pedal shown here with a seemingly brand new unblemished yellow case is a reissue already?


Here are some stills:
