Great story, John, as usual.
Sometimes we forget about what technologies were not yet available.=C2=A0 B=
ack in those days plastics were not as prevalent and were rather expensive.=
=C2=A0 The alternative to this process was to stamp steel.=C2=A0 In fact th=
e TR3 tunnel was steel and it was the switch-over to the TR4 where this fib=
re-based process was introduced (at least to the TR line).=C2=A0 Sure, they=
could have used glass-fibre but the set-up time is more along the lines of=
an hour rather than 30 seconds.
These days vaccu-formed thermoplastic parts are cheap, resilient, water-res=
istant, long-lasting and don't smell of fish.=C2=A0 I'm sure B-L would hav=
e loved it had it been available at the time.

I have very vivid memories at age 16 of going with my Dad to a UK company c=
alled Prestfibre and watching the tunnels and instrument panels for Herald =
and TR being made.=20
The solution of mashed paper, cardboard was spread over a male former made =
of perforated zinc and then the =E2=80=98goop=E2=80=99 was covered by anoth=
er inside shape former to which pressure and heat was applied. Thirty secon=
ds later a sort of tunnel or panel was pulled off the inner former and plac=
ed in a pile alongside to cool. What stands out most in my memory was the s=
tink of raw fish as fish glue formed a large part of the =E2=80=98goop=E2=
=80=99 mixture. Unfortunately the fish odour lingered around each assembly =
for many months and made the cars in which they were later fitted to stink =
of fish as well!
It took a very long time - at least two years - for Prestfibre to find an a=
lternative glue whi ch didn=E2=80=99t stink of fish and while the cars them=
selves no longer smelled of fish, the durability of those =E2=80=98goop=E2=
=80=99 fabricated items were by no means as long lasting. I guess that=E2=
=80=99s why y=E2=80=99all are considering alternatives?
