Kreig-
You have some good questions.  Dad is having some internet issues so I will
try to answer your questions.

First, I did not notice your serial number in your posts.  That will help
with what is correct and what is not.

Next, the radiator cap on most 1930's had the wire clip under AD641 which
was D1567R, D1568, & D1569.  In the 1931 parts book, AD86 replaced AD641 and
the serial numbers are not present.

Toolboxes had a hole and most of them were mounted so the hole came out the
front and it did indeed hold the hose of the grease gun.  We have often
wondered if individual assemblers at the plant took the liberty of placing
lids on differently or mounting the hole to the back.  The majority we have
witnessed are to the front though.  I have never had a toolbox with a hole
on top and suggest that it was a farmer modification.  All standards had a
hole in the toolbox.  Widetreads did not have a hole and mounted on the
transmission cover.

The lever to engage and disengage the PTO is C1621 for Standards 218675 and
up, WT's 402040 and up, and all orchards.  Prior to that, it was the 90
degree lever that went right into the transmission case as you described.

The radiator sides are C257R, C1910R & C1911R.  The latter two are left and
right sides for the big bore tractors.  C257R was for small bore tractors
200111 - 223802.  The early style did not have a bolt hole through them to
attach the air cleaner because the early tractors had the air cleaner down
low in the belly pan.  The retrofit kits the dealers installed took the air
cleaner out of the belly pan and raised the opening for air to enter outside
and above the hood.  The 1930 tractors had the hole in the radiator sides
and the pipe to bring air in went through the hood and above it.  Some late
1929 tractors also had that same style.

Power lift was used to raise the mounted implements on the GP's.  Standards
had PTO and Power Lift as options, Widetreads had them as standard
equipment.  We have a 3 row mounted cultivator that will be demonstrated at
the show in a few weeks.  The buck rake also used the lift as well as the
two way mounted plow.

Hope this helps.

In regards to the GP's, I am interested in knowing more simply because I own
one.  A 1930 GP in good running condition, needing a few parts here and
there and not really knowing what parts are needed.  Have been looking at
and comparing GP's at shows and my impression is that no two GP's were EVER
built the same!!!

Seems there are about 4-5 ways to run the spark plug wires, about 10
different configurations for air cleaners and exhaust.

I found an original tool box off a parts tractor and am finding they came in
two versions, one with a large hole at the front and some without. In
pictures i see some holes are empty while in other pics I see there is
something attached.  In conversation this last weekend I was told the hole
was made to accomodate the "dirty" end of the grease gun.  True???  There is
a small hole on the top of the tool box and appears to have no function, no
knob is seen in the parts catalog.

Never could figure out what kind of handle was needed to actuate the PTO.
Some tractors have a non-removable 90 degree handle for the PTO while others
seem to have a missing handle.  This last weekend I found the "correct"
handle on a 1935 model and will make a reprodution for my 1930. This looks
like part number #AC-573-R   Hope this is correct.  I also see in the parts
catalog, number C-2118-R.    There are no part numbers on this handle.
At the show there was a 1930 GP next to mine with the 90 degree handle, go
figure!!!

Also the radiator casting #C-257-R    seems to come in two versions, one
with a bolt hole on the right side to attache the air cleaner and the same
casting and casting number without this mounting hole.  Wondering why I have
the mismatched set of air cleaner/radiator setup. Thinking if it is worth
picking up a replacement radiator casting to make things "correct".

I was surprised to look through the owners/operators manual and there seems
to be no mention how to operate the machine, how to activate the PTO or
anything else, seemed rather strange.  Have never seen a GP with power lift
and not sure what it is designed to do.

Ok, I guess that is enough in one posting.
