Vintage craftsman saw model # location?

[Tunajoe]

I picked up this saw for a good price but it's missing the side rail extensions.
Coincidently, I saw a Craigslist ad for a homemade bed extension that looked very well made for $65.
The ad says it will fit model 113.22401
I have looked all over my saw and can't find my model number.
Any insight?

The tag should be on the lower left viewing from the back (motor side). Yours apperas to be missing. Look for two rivets or their holes in that area. Most of those saws are very similar. I would think some measurements of the top would verify if it would fit.

The tag could be hiding behind the motor mount, towards the bottom of the case.

Sounds right, I have one I got one that has the tag right behind the motor.
