Help identifying Mossberg 500 model shotgun

[starbucksgold]

I am looking at purchasing a Mossberg 500...or at least that's what the seller is calling it. It does look like the Mossberg 500 JIC but the owner does not know what model it is since he does not have paperwork. Does anyone know how to truly identify the Mossberg model? He provided me a number located near the trigger: T662352. Seller indicates it's a .410 model. Thanks in advance.

I thought all 500s had the mossberg 500 writing right under the gun where the magazine tube is, under the action. Both of mine do, a cruiser and a regular style one.

the specific model # should be on the bottom of the receiver at the mag tube
