Craftsmen Converse

Yesterday I was removing the window casing from the living room windows. After prying off one of the vertical side pieces I noticed this wedged in the space behind.

In pristine condition with the imprint, "Made in Germany" . I would guess a rose wood handle, pinned with small brass nails through a brass collet. It's very small, only about six inches long and it was once and most certainly wielded by a fellow carpenter in 1927 when this place was built. My first thought was did he miss it? At the end of the day, as he touched pockets and checked bags, did he scratch his head and say, "what the sam hell happened to my little flat head?"
Forgetting that he had momentarily wedged it into the window sill to pry it away from the wall ever so slightly as he nailed in the two-piece reveal.
I forget many many things, as those who know me would attest. But I can, with a decent degree of certainty, tell you which box or bag or cubby the red handled wire strippers are. I would have missed this little flat head. It's pretty. And I dig pretty tools.
