What are these needles?
I've been cleaning up accessories and miscellany in the recent acquisitions and found one of these needles, by itself, and thought, "Wow, someone really slammed this needle into something."
Then I found three others in a package. Laid next to each other they are all bent the same. Coincidence? I guess I have to allow for the possibility that someone slammed 4 needles into the exact same something at the exact same angles and velocities. Or, were they made this way on purpose?
They have Dotec 75 11 stamped on the shafts.
Anybody have any thoughts? I know there are some really old machines that take a curved needle, but these don't look like that.
