Hello everybody.
I am in Greece and I have just acquired a M38a1 12/53 from a yard.
It was left untouched since the day it left the Greek army.
Some info :
1. Fenders with diagonal seam (pre 1953)
2. battery cover 8 thumbscrews
3. hinged grill
4. no supports on top of radiator.
I will keep you updated with my progress...
Regards
Kostas |

Let Me properly introduce my project. I did some hood number "digging" and after 6 or 7 layers of paint I was successful.
S/N :67463 (front of passenger seat and tab behind passenger seat)
Del date:12/53
Hood number 20989745
1. Fenders with diagonal seam (pre 1953)
2. battery cover 8 thumbscrews
3. hinged grill
4. no supports on top of radiator.
Unfortunately, above the number everything was erased by a big "bare metal" --> rust scratch.
I managed to get the U.S. but it is missing. Based on the numbers and what I have read, I understand it should be U.S.A and not U.S.Army, but if any "grown up" can assist is more than welcome. |

Thank you for your reply. I guess I was completely wrong...
Although I could identify clearly the numbers, I could not see the letters.
This was mainly because of bare metal scratches above the numbers and some sticker. The vehicle was full of reflector stickers under the last greek army camo paint. The coating under the camo was bright yellow. I guess it was used as a follow me airport vehicle at some point of its service life in Greek army. Tomorrow I will post some pics... |

Hi everyone. I am starting taking things apart in preparation for sandblasting. I am struggling to identify the correct bolt description.
I found in the manual for example the bellow description: "BOLT, ASSEMBLED WASHER, int-teeth lock washer, hex-hd, header-pt, S, cd- or zn-pltd, 1/4- 20NC-2 x 5/8"
Can anyone explain to me especially the 1/4-20NC-2x5/8 part? |

So let me give it a try :
1/4 bolt thread diameter
20 : threads per inch length
Nc: national coarse
2: strenght grade
5/8: length
So if I am correct I am only missing:
header-pt, S,

Those abbreviations and manufacturer's codes are listed on pages 5, 6 & 7 of your M38A1 parts manual ORD 9 SNL G-758.
Also there are several good web sites that explain the fasteners annotations in great detail:
https://www.boltdepot.com/fastener-information/measuring/notation.aspx
https://www.boltdepot.com/fastener-information/type-chart.aspx
http://www.boltscience.com/pages/glossary.htm
https://www.sizes.com/tools/thread_screw.htm
https://www.eaglefastener.net/technical/screw-point-styles.html
In the case of your example: BOLT, ASSEMBLED WASHER, int-teeth lock washer, hex-hd, header-pt, S, cd- or zn-pltd, 1/4- 20NC-2 x 5/8"
BOLT, ASSEMBLED WASHER: Abolt or screw with the washer prefitted and stays in place on it's own.
int-teeth lock washer: the type of washer attached to the bolt/screw
hex-hd: Type of head on the bolt/screw
header-pt: the type of point (header-point)
cd- or zn-pltd: The type of plating used. In this case Cadmium or Zinc.
1/4- 20NC-2 x 5/8" : Dimensional info for bolt/screw.
1/4 = 1/4" diameter
20 = 20 threads per inch.
NC = National Course a thread classification.
-2 = Tolerance standard: Quote: | old American National series had four classes of tolerance: Loose-fit (class 1), Free-fit (class 2), Medium-Fit (class 3), and Close-fit (class 4). |
x 5/8" = Length _________________ Wes K

You even have the horizontal rods for the bows! |
I actually chose this one after checking more than 20 m38a1's.
It was the most complete I found.
A few things need replacement, but missing items were ONLY:
1. 1 wiper arm
2. Steel pipe between carb and air cleaner
3. 1pc front shackle is m151
4. Hood thumb bolts
5. 5th wheel
6. Emergency brake shoes and level. (Handle and rod are ok)
7. Horn rod and small cover.
8. Jerry can
9. A few bolts.
The main reason I chose this one is the fact that it has : old fender design, battery cover old type hinges and no radiator rods and of course front dataplates mach behind passenger seat dataplate.
And NO MOD'S... only one small door bolt lock to secure the pasenger seat and a couple of holes on front bumper. It was straight from the army. |

Thank you for the info.
I will try and take some photos over the weekend and post because it looks like an ugly mod.... |
