What is this plane?

Confusing, I think we may be looking at two different planes.

You are looking at two very different planes, and the ”#10” is a Frankenplane, too boot. Lever cap is off of a “Four Square plane, or a trans plane.

I would try for BOTH planes, as the second one looks a bit like a #2!

Wow! That is interesting. The lever cap looks to be a Four Square cap. Other than that, I got nothing.

-- "hold fast to that which is good"

The handle on te side view is the furthest protruding part, But, on the top view that is not the case.

Looks like a Stanley No 10 to me.

Whatever it is, he should put a pillow case on that thing or stop dipping in his sleep. Ewww.

Looks like two different planes to me. The #10 should have open sides.

I agree, definitely two different planes, look at the difference in shine of the finish on the front knobs.

You aren’t seeing the handle on the top pic, it’s the blade iron you are looking at.

2 diff planes based on the broken body (front right side) on the side photo, but does not show on the top photo.

I would contact the seller, sometimes sellers just throw some pictures that they have on their camera not knowing when it was taken or to which plane it relates to as long as it looks a bit similar (not everyone selling woodworking stuff are woodworkers)

The shadow one the first pic indicates an open side. The second plane may be a 3 or 4, but not a 10. Stef is correct on the pillow case however.

No lateral adjuster on the 10 either

I agree with ShaneA , alternate planes ? , but I disagree on the pillow case, it is lovely and maybe even of the same vintage as #1.

I sent the seller a question. We’ll see if he responds.

I say they are the same plane. Although what Shane says about the light is compelling, the handle could have reflected the light to produce the open side look. Remember that simply because a plane has a base that says Stanley No 10, doesn’t mean it’s not been taken apart and had other parts from other planes installed. I do that myself with irons and caps.

He could have just uploaded the wrong pic, after all, to many people a plane is just a plane.

Look what my search for a Stanley No.1 turned up…

-- Do or do not, there is no try
