Looking for a flyback for a RCA CTC 15

[jsandlin]

I finally found an RCA roundie.
The good:
It looks to be a low hour set most all tubes are still originals.
The PCB's have little to no heat damage.
The cabinet is spotless looks like it is right off the show room floor.
The CRT was replaced in 1968 with a RCA Colorama checks almost NOS with a Sencore CR70.

Now for the Bad:
The flyback is burnt.

So I am looking for a replacement flyback part numbers are:
RCA 113382
Thordarson Fly 277
Triad D304

Any help in finding one would be appreciated.

Thanks
Jim
