Older Mac tool box questions.

[Musicinabottle]

I bought an older Mac tool box that's in fair condition. I was just wondering what model it is, how do you tell, and how to access the lock mechanism. I'll go out and snap a few photos of it today, but it's a 10 drawer road box. You open the top lid and there's a lever at the rear of the box under the lid, that flips to unlock / unlock the drawers so that the drawers can be accessed with the lid closed or not. Some of the drawers lock and others don't. It has 3 rods that go on the back of the box and they move freely and the springs are intact but two don't drop on their own when you hit the lever. Tap on the box and they drop. Was attempting to oil everything, but how the heck to you get in to the covered latch mechanism? I see the screws but the shroud won't come off, easily anyways. It has 3 bottom drawers, the lowest is a bit larger, 6 upper small drawers in the middle and far right and one large drawer at the upper left.

It should be stamped on the side. Sounds like an MB510

Thank you ZK. I need to get batteries for the camera, so photos are still coming, but I'll check that out because the box needs a new lid catch for the left side.
