RCA drawing number 1456502-501 crosses to RCA part number 130093, also, Thordarson number FLY-439. It's a flyback transformer used in RCA chassis CTC-41 and CTC-42, 16 inch hybrid portables.

Thank you
It's been awhile since I cross these.
I remember crosses on microfiche.

I could not think of the correct name of drawing number.
Was there a cross to model numbers from rca or was that yours or someone else that created that cross?
The other number is that date code and other info?
Thanks
Doug

Yes, the 274 is RCAs EIA? code number, 70 probably means 1970, 24 may be the week of and 3 is the day of the week. I have a drawing number to RCA part number catalog. Last week I looked up several flyback numbers for a friend who came into a stash on NOS RCA flybacks and I remember finding what chassis went with what transformers by checking service information parts lists.

Sounds right to me. RCA parts boil down to a 6 digit ## issued consecutively.
The 274 is the EIA code for RCA so RCA BUILT that part.
" Drawing" numbers are on big parts such as FBT's. Most end in -501
but I never figured out any pattern with them. We did have a paper cross
for drawing to 6 digit part ##
Other numbers were used like KRK for tuners, CTC color chassis, M for modules & other sub assys.
In the end the 6 digit ## is the start for finding parts.
