I've made these a while ago, but some of the shots were little blurry so I didn't post it, thinking I'll make better ones later .. A couple of moths later I still don't have much free time for this kind of things so I've decided to post as it is, in hope it might be useful for people hunting the ultimate graflex for their ANH build ...
Here are the 3 types of graflex tops with "shiny" beertab rivet that I'm aware of:
1. I've only seen this type on a Folmer NY no patent 3 and 2 cell flashes, this particular copy is from a 2 cell:

besides the specific button and glass eye it also features straight pins and a single big rivet in the bunny ears.
2. This kind of configuration I've seen mostly on Folmer with patent 3cells, but it is also relatively common on Inc. 2 cells and I've seen one or two on 3 cell Incs. This particular one is from a 3 cell Folmer with patent:

The rivet on this copy is little worn and scratched so it does not "shine" as much as the others, but even under the weak light coming from you window you can still notice the distinctive reflection pattern is showing.
Features straight pins and a single rivet that has a hole in the middle. Also on these flashes the clamp lever is of the type where the rivet sits really close to the edge (image borrowed from Drew Barker's earlier post)

3. The Classic "Inc" top - found on most Inc 3 cells and 3 cells . This one is from a 3 cell:

Pins have the distinctive "Inc" shape, the rivet on the bunny ears is the same type as on 2. above, but there are 2 recessed "dots" near the edges of the parts.
There is also some difference in the washers under the beertab - 1. is chrome like the rest of the flash , while 2. 3. are more yellowish like brass, but I could not capture that detail well in the pictures.
