Cleans up nice
See look
Like somone bashed it with the hammer
Definitly not me
I leave it alone

Beveled babbitt ?
Perhaps they made a mistake, and fixed it.
Large babbitt bearings for motors are often fixed by building up the surface with new babbitt, using a gas torch.
And old autos had the joints filled with lead.
Some interesting creativity in this engine.

Dont know
Bud it looks like its meant to be there
Maybe not
However thanks for mentioning the shim trap
I almost didnt see it aswell

That is a bit odd, but I have seen some odd stuff on old steam engines.
I saw one engine that had bearings that were made from two pieces, soft soldered together.
Perhaps someone made a replacement bearing from scrap pieces that they had laying around.
One never knows exactly what one will find on an old engine.
The Cretors line of steam engines were pretty consistent, with an occasional oddity on some of their early engines.
Perhaps that is just discoloration of the metal, but it sure looks like babbitt fill to me.

It looks like 45degrees milled off and
Eighter lead Lead and zinn
Or babbitt maybe cast on
I get a better pic

Softsolder shouldent bubble up that badly
Especially with brass

Sort of looks like sand inclusions.
Gas bubbles generally have rounded surfaces.
Sand inclusions have an irregular ragged outline.
Could be pockets of slag too.
They really did a good job of adding that onto the casting.
They sell babbitt damming putty, and you can mold it around anything, and pour babbitt into the pocket that it makes.
Using babbitt for bearings is an old technology.
One book from the mid 1800's I read referred to babbitt as "white metal", and said it should not be used because it wore out the journals.
Of course now days you can get babbitt in various grades of hardness, and it does last a very long time, even under heavy loading, if kept well oiled.

The sliders
Well it is unlikely to be an oil point a sthere is a hole for that at the top of the rod. Possibly just to close the hole and then take it out to enable something larger to be screwed in when you want to pull the pin out. Though I can't see anything that stops that pin from sliding out so could be some way of retaining it.
The piston looks like it had a thin plate soft soldered into it to close the void, this keeps the weight down but reduces dead volume within the cylinder

Other side got the same
Bud screw missing

As there doe snot seem to be anything to stop the pins moving sideways it is possible the screws were for a cap, much like a decorative washer which being on both ends would stop the pin working it's way out.
Rings are usually made from cast iron bar, I doubt an engine of this size and build detail would have used packing in the grooves.
