Hi, thank you very much for your interest and comments. Hope this build can be of help to anyone rebuilding this M60.
The following set of posts are for the M19 commander's cupola. This item is a model on its own and requires a lot of work. It is the least accurate part of the TONGDE M60.
First task is to perform some research and compare to what TONGDE has provided.
The M19 cupola is cast and a bit rough. You can see below that the cupola is round, but the visors require flat surfaces.

Suberb picture of an M60A1 with details of the right side, view under the cupola mantlet and overall view of the mounting brackets for the ERA.

Opened M19 cupola hatch. Notice the structure of the hinges and the lack of handles on the hatch.

Right side of the TONGDE cupola. The base is there with overall good dimensions, but not much details. The lack of flat surfaces for the visors is a major dissapointment. It is the first thing i noticed when i saw pictures of the model earlier this year. It would not have required much more effort. Now, every owner of this model has an M60 with curved visors on the cupola... The handle on the hatch must have been added for convenience for those wanting to open the hatch, but it has to go.

A small design mistake on the hinge that need correction. That section on the right need to move to the left.

The mantlet cover is weakly detailed and has embedded turret component. The whole frontal area needs rework. Notice the curved visors. Sorry, but i just can't stand it.

Breaking the cupola apart. Easy, the two halves are not glued, just held with screws. Ah, thank you.

But that hinge is glued tight. Hard to remove without some destruction, but i managed.
