This may be of interest just pulling down a motor at the moment and the three different plugs that are used.
Left side of block sacrificial anodes (core plugs) as you can see they have been sacrificed. Note this S1 has alloy water pump would never have heard of coolant still had water in it from when it was last used 15 or so years ago and the pump and intake manifold are perfect so they did their job.

I am about to go through this same exercise, replacing the frost plugs in a 2.25 series IIA motor. the casting plugs I am looking for are the brass type water jacket plugs, but seeing that I can remove all of the freeze plugs fairly easily, I intend to write all the block plug sizes down in my parts book next to the part number for the core plugs.
Cheers Arthur :D

Found some 1/15/16 brass ones if they are the right size

It is one of numerous designs of "core" or "freeze" plugs, which include the Welch, the cup and the solid threaded designs.

In a series Land Rover there is no shoulder in the core holes so the cup design of core plug is used.

* Your post "original title"
Sorry Russell the clue is in the last pic. Will leave it open for a bit to see if an other takers.
Only 3 other types.
The rear plug hole in a S1 block has the lip and often found with the flat type plug.
Easiest to fit when doing a repair through the firewall inspection hole.
