A couple of years ago, I listed all the fixed-wrist klickies and sent the data to Heather. She added it to PlaymoDB. Whilst there was some 'flexibility' in the exact make-up of klickies in the 1970s (mainly I think hair colour being different from the pictures on the box), I am confident this combination of arm, leg and torso colour never appeared in an official set. The nearest would be yellow torso, red arms, red legs in sets 3542, 3550 or 3187x. Or red torso, red arms, white legs (in 11 sets). Even Marx toys (UK made) did not have the combination your figures have. So, for me, they are customs!
