My father tells me they shifted the relationship a step during WW2, and
really old Whitworths have a bigger head. I ought to ask the Vicar, his
steam engines are old enough for that to crop up.

Probably 3.7mm Whitworth...

Seriously, the series construction was in the era of Imperial bolts, and
a lot of them were Whitworth threads. In a lot of places a metric nut
and bolt would be fine. But be consistent. Don't have three metric and
four Whitworth holding the wing on.

(And the lens-mount thread on old Leica cameras is apparently Whitworth
profile, Imperial pitch, and metric diameter...)

Aha - first problem. I doubt you'll find any other vehicle with as much
of an assortment of different threads and sizes as a series Landrover.
Depending on the year the will have a mixture of some or all of the
following: BSF, Whitworth, UNF, UNC and metric. In accordance with
Murphy's law, the commonest size on *your* Landrover is the one you
haven't got a spanner for.

2nd problem - most of the ones you'll need for rebuilding are likely to
be specialised fasteners anyway (door hinge bolts, etc) so you'll
probably end up buying them "on demand" when you need them. Quite apart
from which, bolts are bloody expensive - you probably won't want to have
a lot of money tied up in bolts on the off chance you may need them.

Because bolt size and spanner size don't always correlate eg an M8 bolt
commonly has either a 12mm (JIS) or 13mm (ISO) head. Also the thread
pitch can vary - "normal" M8 is M8x1.25mm, but 1.00mm is also used.

But the Leica thread became a classic for compact cameras, especially when
the cheap Russian Imitations flooded the market.

Same could be said for the Pentax 42mm thread that had a long hold until
they eventually succumbed and went bayonet.

I still say from the latest digital Pentax to any of the older post 42 mm
thread varieties you have access to the widest set of lenses available, as
even the digital body can take the old screw threads with an adaptor.

As for versatility I like the K1000 a sort of series go anywhere Pentax

whoops that is totally OT

Because the heads are not always the same size for the same size of thread.

In general.........
M3 = 5.5mm spanner
M4 = 7mm spanner
M5 = 8mm spanner
M6 = 10mm spanner
M8 = 13mm spanner
M10= 17mm spanner
M12= 19mm spanner
M16= 24mm spanner

The japs tend to use smaller a/f sizes for the same size thread.

But, all this talk of M.etc will be irrelevant if you are building a series,
as you will be into UNC/UNF and whitworth.

The whitworth system is far simpler, i.e. you tighten a 1/4 whit bolt with a
1/4 whit spanner!

Sold mine, and wish I hadn't. Dad had a Spotmatic, and my Mum GAVE IT AWAY
to a relative who expressed a vague interest in it, when he died. I was
completely gutted. By the time I found out, he had lost it, or sold it, or
something.

A "Series" camera - I like it.

Actually, while Whitworth were used to some extent, most of the body bolts
(which is what you are mainly talking about here) on Series one were BSF,
or BA in the smaller sizes. The BSF gradually changed through the early
sixties to UNF, and by the end of Series three production some metric sizes
were creeping in (But my 86 110 still has a lot of UNF).

Probably the most common sizes are 1/4" UNF in 1" and 1 1/2" lengths, and
5/16" UNF in 1 1/2" and 2" lengths, and 4 and 6 BA 1/2" or 3/4" long. In
Series 1 (+S2 & early S2a) the UNF would have been BSF. All body bolts and
nuts should be galvanised (not zinc plated) or, for Series 1 (early at
least) Sherardized - which is virtually unobtainable today.

Many Landrover owners replace these with metric sizes, and it is up to you
whether you do this. Some use stainless steel, but this must be done with
caution, avoiding electrical contact between the alloy body panels and
Stainless steel. In any case, use anti-seize compound in assembly.

The SLR 110 was a superb camera - a real camera, but with a compact
film format and it really did fit in a pocket. Results were
suprisingly good, but film was limited to tourist-fodder stuff. No
slide film and no really slow or fast stuff.

I moved from Pentax (I used to have a Super A and an LX) a few years
back to an EOS. Far more useable than most Nikon's, but probably
lacking that nth degree of robustness.

The best pictures I ever took were with my (original) Olympus Trip. A
cracking lens, easy to use and somehow much better than any other
camera I've had since. I think it's because there is only one thing
to think about - i.e. what you are pointing it at.

One point about SLR's, which also applies to Series Land Rovers, is
that they have to be used. My Dad has one of every Pentax SLR ever
made up to the mid 80's when it all went wrong (a strange thing to
collect, but there you are). We were going to take a couple of
Spotmatics on a trip just for nostalgias sake and had to abandon the
idea. The shutters had all siezed slightly - not enough to lock
solid, but enough for the rear curtain to lag behind significantly.

The Fed-2 is quite good.

Check my brother's photo site, and the Ely cathedral pictures, at
jfbell20.fotopages.com -- I think he used his Fed for that, a fifties
design, while the lens is a piece of 21st Century kit.

I have an old spotmatic too but the meter is none too reliable these days.
The K1000 though goes on for ever, I also like the ME supers, nice and
compact. Olympus were the original compact SLR and then Pentax made a rather
unsucessful 110 SLR of all things, but now SLR's have got bigger and bulkier
again. Why Nikons had such a bulky motordrive I'll never know, completely
over the top but at the time it marked out the press photographer, (who seem
