Thank you guys. The tractor actually has two serial numbers. the original Ten was PT3292, but the block cracked so my grandpa got another Ten PT4709 and swapped the 4709 engine onto the 3292 tractor. My grandpa bought this tractor with his pa when he was in high school and the used it to cut the edges of the barley fields with a JD No. 5 sickle bar. My grandpa and his pa, bought the Ten 2nd hand in the 40's and modified it to match their other Cats.
The original filler neck on the gas tank was removed, and patched and the filler was moved to the top of the gas tank.
The seat has been cut to match that of a Cat Twenty Two.
The fenders have been shortened to move the seat bucket forward and up over the PTO lever.
New holes were drilled to move the gauges to the other side of the dash board
A Temperature gauge from a WW2 Willy's was added
Oil filter was added
........and tons of other modifications......
If anyone is in the area she's a very unique tractor and i'd be more than happy to show 'er off.
P.S.
I have the carriage and transmission for the PT4709 Ten, The Grousers are BRAND NEW wide gauge, you can still clearly read "Caterpillar" in raised letters on them, grousers have no rounded edges. The track bushings have been rotated and show some wear, but the tracks don't have any slop between the pins and bushings. Anyway i'd like to restore this tractor to stock, red n' grey the whole nine yards, but don't have any parts for it except for what is in the pics... anyone have an engine?
