The new defective TR6 set I just installed are made in Taiwan.
I just looked in my collection of NOS ones and I have 4 new .020" Spit
County Pistons and those appear to be made in the UK but they are likely
10-15 yrs old or better.

Where are AE pistons made?

Yes the County Rockers are made in India.
They usually have better quality control than most.

Another horror story:
A while back I replaced my Spit's rocker arm shaft with the part that
most vendors sold. I believe it was "County"
branded, and it was made in India. I went to adjust the valves a few
days later, and I noticed that the front four rocker arms
seemed rather oil-starved. When I ran the engine with the rocker arm
cover off, I could see that only the rear four rocker
arms were getting lubricated.
It turned out that the shaft was not completely hollow: They had
rifle-drilled it inwards from each end, but they did not drill
deep enough, and the two holes did not meet up in the center.

FYI
I am in the midst of a TR6 Rebuild with an engine that is .020"
overbored.
While fitting up the pistons and checking clearances everything
checked out and the bore was concentric and to specs.
With the piston installed in the bore I noticed increased drag
with #1 piston installed.
With rings gaps, skirt clearance correct I pulled the piston and
didn't see any issues.
Further inspection showed that the piston was cocked in the bore
and had score marks on the bottom of one skirt with the same wear
just below the oil ring on the other side.
After inspecting it with the machine shop we noticed that the ring
grooves were not fully machined on one side of the piston.
The rings would not move far enough in the groove and was proud of
the surface causing the piston to cock in the bore.
We collectively have not seen this before and have a new set of AE
pistons not County on the way.
Having spent many years in Automotive Engineering at one of the
former Big Three, these events are usually not one of's.
There likely are many more out there that ran down the line in the
same batch at the same time before it was caught.
These are new County Piston sets (I think made in Israel now).
I would inspect their parts very closely before you install them.
I also noticed machine chips in the machined groove of their
Tri-Metal Main Bearings (Israel).
The chips were in the machined groove and were plated over with
the babbit and copper.
I have had very good experiences with their parts in the past.
Just thought I would provide a heads up.
