Which Holley carb is this? (need to rebuild)

[89GMCSuburban]

My friend just gave me a Holley carb that needs a rebuild, but I do not know what model number it is, or for that matter, where to look if it's on the carb...so....

It's a Holley spreadbore
standard finish
Manual choke
Vacuum secondaries
single accelerator pump

What is this? I tried looking on the Holley site, but could not find what it was... thanks in advance, guys!

look at the front face of the choke horn. It will say something like "list 1850-1" or something similar. Usually a 4 or 5 digit with maybe a dash 1 or a dash 2 after the main #. I have some holley books. I'll check #'s also

It says LIST 8700 and below that is 1079...
