Technical Help identify what year this Edelbrock Performer intake was made

Found this 2101 Edelbrock Performer intake recently and would like to know if anyone can figure out when it was made/used.

Thank you in advance.

 

This one is RPM , like 90 ish ,
Us less I have this one confused with multiple others that I have .

Its not cast USA , nor patten #
Seem made USA 2000's on top .
I have a few other older Performer ,
Not able just to put hands on.
Afew years ago You where able to
Contact Edelbrock before they left
West coast , with right contact you cold get information out of the archives
Look faint to say 1289 or 1299

 

I’m putting my money on April 29, ‘99, but the 29 does look a little sketchy.

 

What does the top “Edelbrock” script look like?

 

It looks like there are pictures of two different manifolds.

 

That poor thing has been through the wars. I'd strip it down and find a shop with a "cold tank" that they clean aluminum heads and stuff in and have it cleaned. It looks about like one I have had since the 80's but I'd have to dig in the shed and find it. That script says it is one of the earlier performers though.
