Hi, does anyone know if this is a original cone for a 515B? It does not say 21184, for example.

100% certain it isn't the cone that came in the speaker.
I don't have ready access to my papers, but that looks like a number from the 80's 90's era. So I think it's an Altec part, but way newer than the speaker.
Your neighbors called. They like your music.
That's a number assigned by Electro-Voice when they took over Altec. According to my cross-reference that cone, the 18-03-035400 replaced several Altec cones; R416/515-16; R515; R416-8; R604-16E,8K,8H,8G; and the R26768 whatever that was. So you do have an Altec cone manufactured during the period that EV owned them. It is not clear if the manufacturing specs were the same .... maybe someone else can chime in to clarify.
I wondered about the EV connection, but it's what GPA has and the few GPAs I've seen looked just like OEM, which these don't, so was wary: Altec Lansing - Page 120 - diyAudio
Another thought was these were heavy doped for 515E.

Thanks guys, so what does this mean from the point of view of sonics and valuations?
Were the later ones not as good, or more like the E, and have less valuation?
You have to define 'not as good' since woofer specs changed over time to accommodate ever increasing amp power, higher damping factor and the increased average/peak SPL demanded.
