Ithaca semi-auto probably a model 51 field strip ?

[RobSmith]

Someone asked me to show him how to take his new-to-him shotgun appart for care and cleaning, he only knows how to take off the barrel. I'm not familiar with this specific type, it's a semi-auto Ithaca, looks like a model 51 (I foolishly didn't think to write down the model number when I handled it over the weekend but it looks like a model 51 anyway).

Can anyone post a link to the manual or general instructions on how to take this thing appart ?

A common method on a lot of semi's is that you just pull the bolt handle straight out (it's only held in by a detent ball & spring), then you can slide everything forward out the hole the barrel was just removed from.
