What is this "bubble" on the bell of the engine on the Apollo-Soyuz Test Project's Apollo service module?

Are there photographs of similar conditions on the CSM engine bells from other Apollo missions? |

No idea, but not a big deal... the coating does its work (protecting the Colombian/Nobium nozzle) on the ground; not relevant once in flight. |
