Help identify 2H early vs late type (2 Viewers)

[Rackety]

Hi folks, recently acquired this 2H, history completely unknown. I believe I have identified whether it is early or late type, but I don't want to influence anyone by saying what I think. I'm completely new to diesels in general as well as this engine, so I've come to the experts here.

Before I start disassembling to see if she's sleeved, what do you think? Early or late?

This is an early 2H.

I have a few comparison photos etc at my diesel site.. scroll down to "Early vs Late 2H/12HT"

edit:

Additional information - I need to correct my post.. the block is late, the front timing cover is early.. thanks to Tom Lance from the Facebook group for the correction and information. Images at the link below updated.
