JCB 1400b Oil Change

[kkcomp]

New to me 1987 JCB 1400b. Went to change the oil and ran into a WTFO. There is no oil fill cap on the top of the engine. Can anyone tell me where to add the oil? In the picture the Black arrow is oil filter Green Circle is dip stick and red circle is where I suspect oil is added but would rather confirm first.

Does that have the perkins engine? 1004?
That red circle looks like the fill on my old jcb telehandler with perkins.

Thanks for the reply. After much digging and searching I found a manual for the backhoe and it confirmed the red circle is the oil fill
