That's not any Model M I've ever heard of... Are you sure that's its part number? Or did you read it from somewhere else on the keyboard?
IBM keyboards are identified by their
part numbers. Most Model M's made by IBM (about 1985–91) have part numbers starting with
1. (The most common one is 1391401.) Later ones started with
4,
5 and
9.
There were also some "quiet" Model M's made with rubber-dome switches—they aren't as valuable as those with the original mechanical switches—whose part numbers start with
6 and
7. But I've never seen one whose part number started with
3.
Here's a typical Model M label with the p/n highlighted:

That's what you want to look for.
Wikipedia's Model M page has a big list of most of the known Model M p/n's. Scroll down to the part of the page that says "Features by Part Number", then click "Show" to see the list. Then you can look up your board's p/n there and learn more about it.
There's also a lot of good general info about Model M's on ClickeyKeyboards.com's
"What To Look For When Purchasing an IBM Model M" page.
When you know what your board's actual p/n is, post it here and we can tell you more. Some photos of your board will also help. Cheers, A.
