Default What is this alternator originally from?

I've been working on cleaning up some more of my garage and among the parts I dug out was this alternator. I'm trying to figure out what it was originally on.
It has "1100881" stamped on it. The only application I have been able to find for this number was '69 Corvette 390/400hp 427.
The thing that confuses me is that it doesn't have the goofy fins on the back that I have seen on some of the other Corvette alternators. Does anybody have any ideas? Thanks in advance.

Could be it has a different back, but it is what you deciphered. Seems a lot more were made than cars as I have had a few of these in recent years.
If its not cracked in the front behind pulley could be a good core.

The rear case is late 70s, not the original mate for the front case. This is what happened when they went through the rebuilders back in the day.

Any opinions on value? I've got probably 15 Delco alternators around here. If it has a decent value, I certainly could stand to sell a few. Tested good BTW.

Hate to say this, but If I wanted it to use and shelf the 903. I would like to see it with pulley off. These are notoriously weak just out from the bearing on spokes.
Should be worth 100 bucks if ok for the front case. Your basically selling the front at this point.. may be worth more to a corvette guy.

If the front case is not gouged up & you had a clean undamaged correct rear case for '881, I can see it bringing fairly strong money. As is, at most, a couple hundred & that's for a Corvette guy that is chasing that date range of front, & most likely, has the correct early 10SI rear case.
