Atwater-Kent cap replacement advise needed.

[vintagecollect]

I would strongly suggest just getting rid of that weird black goo. I would be cautious to have good hygeine before and after dealing w/ this. May have pcb or other mystrey chemicals???
I'm sure AK thought it would be in business forever and did this only for people to rely on facory replacement parts.
A cut to size black plastic bottom cover from TAP, w/ holes drilled just big enough for wires to create same effect and easier access for repairs, little black wax melted over plastric.
If you're really bent on reproducing same effect and look, why not make new block out entirely of black wax to cover parts. Repairs could be done by simply putting can in boiling water to melt out parts and wax. Looks the same, just more service friendly.

post pics of set please and parts value info, this sets has always interested me. That cap block keeps most of those sets as display pieces. What year are these? One of my old friends from years ago was big AK collector had one not working for display only.
