Scott, you've found another bit of Rootes history. At one point, Desmond
Kludge appointed an east European, a Mr. Gerald Juri, to head up the
Fasteners Department of the Rootes engineering team. He had spent much
time previously on the production line, and many assembly techniques
used on the cars came to be called Juri-rigged, or Jerry-rigged (the
pronunciation seems to have been in question). He developed specific
fastener markings to reflect varying programs running at that time. I'll
try to supply translations of some of the codes:

*auto

Ah, the famous "Auto-removal fasteners"; it concerned management that
adequate tools might not be available for roadside repairs ( great
foresight, few of us have complete tool kits for our Tiger today!), so
the bolts were made undersized a bit with the intent that they would
unscrew by themselves without tools. 

*crs

Translates to "corrosion-resistant steel"; however, the cost of the dies
for stamping the heads used the entire budget for this program, so the
bolts were made of ordinary steel. Mr. Juri was quite old at this time
and his memory was failing, prompting some of the staff to suggest that
it stood for "Can't Remember Sh*t".

*sparts

You know those "Spare parts" left over after every assembly or
reassembly job? Well, only Rootes developed special fasteners to go with
them. As the bolts were never intended to be used, diameter, length and
thread pitch were irrelevant.

*tr

Bolts failing to meet rigorous quality inspections (heads and/or threads
missing, bent at 90 degrees or more, crumbled in inspector's hands),
would be re-stamped and sold to another UK car manufacturer (you guess
which one) to help defray production costs.

*wiley

Not sure; perhaps someone else knows. BTW, was the box marked "Acme Bolt
Company", and addressed to be shipped to the desert Southwest?

*wwr

Warranted Whitworth Reallyfine; an experimental series including sizes
like 3/8x250tpi, which had equivalent nuts in the size 3/8x245tpi. Juri
explained later that the differential in pitch provided an in-built
"locking" feature, but actually the bolts & nuts were just spec'ed out
by two independent teams.

*is there any reason for this? 

No
