Hot Rods when was this Weiand 6x2 intake made?

anyone have an old Weiand catalog that lists this 6x2 log intake for Mopar-
WC59? Just curious when and how long it was produced.Thanks

 

Not shown in the 58 Honest Charlie catalog (first year for the B engine) but it is in the 61 Honest Charlie catalog. So somewhere in between?

 

Looks similar to an Edelbrock CDP6, suits B & RB engines, 1958-* (All B & RB except '63'-'64 Maxwedge) http://victorylibrary.com/mopar/edel.htm
