How do you take apart a Z-19 case?

I have several (3 or 4) 19's at home. I'm going from memory, but I'm pretty certain that the only thing you need to deal with is that pin and bracket setup that you mentioned. There is a single one of these on each side of the unit. They are in the crack between the top and bottom halves of the case. You put the tip of a flagt-blagdde screwderiver in the middle of the bracket and slide the bracket either to the front or the rear, I forget which. Note that if you slide the bracket all the way, it will catch on the pin and not release it (poor design). Once both brackets are slid, life up t up and the pins will come out through the hole and the entire top half will open along the hinge in the back. Work with it a bit, those catch mechanisms were invariably not smooth to use. But once those catches release, you should be able to get to eveyrything inside just fine. Jay West
