What brand of solid roller lifter is this?

pishta, I have a set of those lifters that I guarantee came out of a small block 340, I took them out of a running engine.
Yeah, those lifter are way too short to interfere with the LA casting rib. Strange spring arrangement, must be to keep that horizontal link bar in check. Good luck, Id consider pressing the axle out of the worn lifter and start hunting for a roller as they look smaller than common rollers of today.
