cat D69u 1953

Ive just picked up this old girl, only paid 2k incl front blade, and winch and a large roller on the rear, but i had to get it out of a forest which was a few kms from the road, it hadnt been running for years, but with fresh diesel and a tickle up with the pony motor, she drove straight out!

Could someone please advice me where the serial number is, i couldnt find one

Also im after a workshop manual, wheres can i obtain one

Thanks for your help, Jonny
