Where is the Engine Code?

[isaacfull]

Hi I have a VW T25 1984 1900 petrol, need to get a few bits and went to look for the engine code???? I'm flummoxed! it may be that its just under a lot of dirt but followed where it should be according to the Haynes manual and no luck! Any advice would be muchly appreciated. struggling to add image.

It'll be a DF or a DG.
If it's mindnumbingly slow it's a DF. If it's fairly slow it's a DG

The engine is usually very very dirty where the engine code is , give it a clean off

Stamped on the block above the pulley/ maybe under a ton of crud.
