A finned piston doesn't make any sense to me. I believe I see both the cylinder and the piston. They are welded together by corrosion. You can see a line which represents the contact point between the cylinder and the piston. I have marked it with a red arrow pointing to a green line in the image. The second image is there because the green line obscures the contact point so I left the arrow but omitted the line.

Your observations are keen and I stand corrected even though there were no openings in the cylinder. I just thought maybe it worked like a worm gear or something. I really have no clue.

Great fodder for the eye -- one of those wow look whats in this old shed.

I would crop off that beautiful wood too competitive with the piston/cylinder combo. Crop at the main bearing junction. Crop the top so that you only have two layers of the yellow whatsit upper left.

In so doing the piston and lesser surroundings play well together... yes, I know that wood is beautiful, but that is the subject of another photo.

Admirable shot, better to have too much on image and cut than to leave off something important (my sin too often).

I am glad you enjoyed the shot dpullum. Everywhere I looked there was nothing but competition. I will give your suggestion a try.

Wow! What a neat piece of antique industrial engineering. First it doesn't have rings! All pistons, even very early ones from the railways had rings. Also that crankshaft it is connected to has almost no throw to it. And notice the unidirectional gear on the end of the crank. An almost cog lock safety style to it. Looks to me like this thing was designed to go only one way when it rotated. I doubt it would have performed like a regular piston as its ability to seal compression would have been very low. My guess is it may have been part of some kind of steam control system? Maybe from the railroad?
Now about the photo treatment. I believe the effect adds to the antiquity of the whole scene. I personally liked it.

Looks like DirtFarmer is most plausible so far spaceblue. I like you, also thought it does something with liquid or your suggestion of steam as I saw no rings. Glad you liked the treatment.

Estetically I like the treatment. It turns the object in an somewhat abstract representation of life. But technically it did detract from my ability to analyze the subject. That rusted line between the piston and its cylinder is now so embarrassingly obvious.

As an admirer of your work H, any tips that might have made the entire photo better?

You are correct about that spaceblue, I hadn't noticed either and I was there. So much for witness observation.lol

Anyone have a clue what this piston did in it’s day……I’m guessing something to do with water. Comment on the photo an treatment of it are also welcome.


Isn't it wonderful how much information is gained though posting of a photograph of this nature. Things I had never thought about are suddenly thrust into the light of day by those with knowledge of such items. Just wonderful.

I like this photograph a lot - as it is. I also see other possibilities but that would require more of the negative. The curved part which has the post going up under it might be transformed to a helmet on a cross with significance of the death of a soldier. More of the negative would be required in order to straighten the post to a more vertical position. Then the rest of the image could be dealt with as need arises to assist in feeling.

My preference would be b/w with proper tonal adjustment. It is very strong with it's current rendition. There is a lot to see in this piece requiring more than a casual glance.

There is no negative Mr. Hill. If there was there would not be much more of it as it is barely cropped just to straighten a bit. Thank you for sharing a Jim Hill version which I can totally imagine.

I think what you're calling a piston is actually is an aircooled cylinder with a piston frozen inside. Have no idea what sort of an engine it might have been. ...... Coot

That has been discussed and may be true, thanks for taking time to comment.

Sorry. Just can't get with it. By negative I meant whatever it is that comes out of your camera.

Frank, once again, you caught my attention and gave me lots to look at and ponder. The textures of the various materials and somewhat subdued colours really make this an attractive "found objects" photograph.
