Well....ran into small trouble....
Needed "channel" to do the skate rail....didn't have any....
so I "made" it.
While that dried I did some more floor details,
IE the gunners platforms and a rib towards the rear.
I checked it for the gunner's hieght.
Then I mounted the foward skate rail,added the gun mounts,
and "test" fitted the rear skate rail.
Then I double checked the gun mount posisions with the crew.
Due to "casting" issues, the foward gun mounts will be a seprate piece.
I also did a little more fiddling with the rear skate rail.
After all this I was looking at the rest of the LVT(A)-1 that I had cut for the foward cab.
I thought hmmmmmmmm....and tried this.
This might work for future projects.
