magic box source

[bob branch]

I am trying to locate a source that makes a device we used to call a "magic box." It was used to drive two accessory pushrods off main pushrod. This was often used to drive flaps with hinge  lines swept at an angle to each other. Most involved an aluminum block which the pushrod  wires ran thru and had machine screws used to lock the pushrods in place. The flaps usually had  a strip type control horn. I saw them somewhere online in the lasts year or two but did  not bookmark it (dummy!). Any help anyone can offer  would be appreciated.

thanks,
