Default SB exhaust ID

Can someone help with a posative ID on these exhaust ram horns I have.
Both with #3932461 on them, one with a RH13 under the number & the other with RH5. Neither have holes for AIR.
This site
http://corvettec3.ca/casting.htm
lists a vast number of fitments but with no AIR they must be early??
Are they worth it for me to media blast & try to sell??

What's the casting dates on the back? 461 manifolds were used on AIR and non-AIR Corvettes from '72 to '80 IIRC.

One is 6 on one side & 14 on the other side
The other one is harder to read.
Looks like an upside down L & 5 &
the other side of the horn looks like 9? 626 & another letter I can't not make out, so 5 digits in total.

Thanks Mike
