The numbers beginning with 274XXX are the OEM number and date code. 274 was RCA's OEM number. The next digit is the last digit of the calendar year, 1954. The last two digits are the week of manufacture. Most parts were dated about a year ahead. I would not expect the numbers beginning with 274XXX to agree very often.
The 1107355-1 is the drawing number. That references the manufacturing data necessary to build the part.
There is a third number, usually shorter and beginning with 7, 9 or 10. That is the stock number. That number is used when ordering a replacement part from a supplier. That number is the one listed in Sams and the RCA service data.
The distributor usually had cross-reference lists that translated drawing numbers into stock numbers so if someone came in with a part in their hand, the parts person would know where to find it.
