BA 747-100 engines?

[Crosswind Limits]

I am sure some wise soul will be able to tell me which engines BA used on their 747-100s. I was told they were P&W but I don't know for certain. All I know is they looked completely different to the RR engines on the 747-200s.

Cheers!

Pratt Whitney JT9D-7, as far as I can recall (although some early ones may have been -3s, but later upgraded to -7s).

Pratt & Whitney JT9D-7 engines on BA's B747-136 aircraft.

Early BA 747-136's had P & W JT9D-3A engines. After the JT9D-7 went into service P&W offered a conversion kit to upgrade the -3A's to -7CN's (CN for converted) which retained a lot of the external bits in the same locations as the -3A but installed -7 internal bits especially the combustion and turbine sections and upped the thrust. BA used to paint -7A or -7CN on the engine exterior as the component location differences were significant and it helped to know what was under the cowls before starting work.

The JT9 was the only option for the 747-100. RRs and GEs were only available until the -200 arrived.
