Weiand 7502, what's it's worth?

Got a free Weiand 7502. But don't think I'll be using it. I figure its a vintage intake for two reasons. Has many of the accessory bolt holes missing, and can't find any info on it on the web. If it's not on the internet, it's gotta be old right?

Can't bolt my alternator bracket to it, and can't run my Q-Jet on it with out some **** adapter. So, possibly selling it for a spread bore style (The 8000). But, I have no idea how much it's worth.



It's identical to this, but a square bore with a lot less of the accessory holes on top, and it only says WEIAND on top with 7502 on the front.. It's clean and perfect, with no damage. Just curious what it would be worth before I go shopping for the spread bore version.

 

sold one on ebay 45.00 buy it now .c

 

The most I ever sold one for was $50
