Q: My Son did a factory reset on his older ipod touch. Now the App Store is gone, How do I get it back?

Try Settings > General > Reset > Reset Home Screen Layout to get it back.

Is the App store hidden by Restrictions: Settings>General>Restrictions?

What iOS is on the iPod? you need at least iOS 2 to get the App store and use apps. If yo do not have at iOS 2 then you have a 1G. Those can go as high as 3.1.3 that you get htere:

You may want to check the serial number on back of the ipod and search it on google. If there was app store before the reset was done, then u may have to update to the latest vesrion avialbale for ur ipod
