Thanks. I just found out that they made these up until about 53/54 and this is the original wiring.

What got me thinking it was rewired is that I picked up a couple tube testers at a hamfest back in the mid 80s. A similar I-177 and a Triplett 3413-B. Both had nearly every single wire in them clipped.
I think this was done to "decommission" them before liquidating them to the public. I spent many hours wiring them so thought someone may have done the same to this one.
