Sounds like an old 1903 Springfield action to me.
Jules La Bantchni, born 1909, died 1983. Owner of Olympic Custom Guns, 2202 Pico Ave in Santa Monica, CA.
Other than that, I can find virtually zero info on the man, other than people saying they had rifles that were stamped J. La Bantchni. Or that they had a rifle built by him. And it appears that he loved the Springfield 1903 action, because from what I've read today, those are the only types of guns I'm seeing listed when his name pops up.
Here's one for sale.

Ignore everything I say, because I have a reading comprehension and memory problem...
