OMG ; )

I think this series of photos was also used in Darwin's The Expression of the Emotions in Man and Animals.

Duchenne en sus experimentos de electroestimulacion, se dio cuenta que las verdaderas sonrisas involucran musculos de los ojos, lo que nos permite darnos cuenta de las sonrisas falsas de las personas, las cuales no lo presentan. No se dejen engaÑAr.........

There are some incredible photos of Doxford Engines in its machine shops. It's hard to believe that all has gone now though and all those skills lost - a shame..

She doesn't look a day older than 25.

Something about that caption doesn't quite ring true. The dimensions and near-center mount are consistent with the *barrel* of an M2A1 or M101 howitzer. Note that the left end is turned down, which is characteristic of the breach end of the weapon. She's using a micrometer to check a boss or flange of the outer diameter near the center mounting point, which is already greater than the roughly 4" ID of the barrel. No "cutters" are evident, so there's no way one could be inserted *into* the barrel. The castellated sleeve is probably internally threaded and engages the external threads seen on the barrel directly behind her.

inspector23, Photographers are not engineers.

I've found in military history research that many anomalies and aberrations occur between the photograph and the caption. "Kurtz" said it best - "Photographers are not engineers".
