The best way to check if an oscillator is known is to look in the jslife collection and the osc supplementary collection. These two collections cover almost every interesting oscillator discovered up to the end of 2014. In this case you should find the oscillator in jslife/osc/o0008.lif.

This particular honey farm hassler can also be seen in the Golly pattern collection in oscillators/DRH-oscillators.rle and oscillators/honey-farm-hasslers.rle. It was found by David Buckingham on June 30, 1976.

Is there a way to make this into a p9 without making a snacker out of it?

Period 60 glider-supported oscillator, and the wick it's based on. Not sure if it's known, I didn't find it in jslife.

Aidan F. Pierce has pointed out a possibly new interaction with a known but underutilized p2 or p3 catalyst that I think deserves a mention here:
x = 21, y = 14, rule = B3/S23

Slightly related, the p22 traffic light shuttle can be skewed and extended easily:

The monomer would be even sparkier, and the spark is more accessible, if you can supply a P18 diagonally-accessible bit, domino, or duoplet spark; unfortunately P6 and P9 don't work directly, but something that produces such sparks might work if it could be made to safely interact earlier.

I'm not finding any prior art on a quick search. When the p13 was discovered in 2009, there was some exploration of ways to share the blocks, as the LifeWiki details. There's nothing that I can find about getting rid of one pair of blocks entirely.

I moved a bunch of discussion from the "unsure discoveries" thread to here. This is definitely the more appropriate location for this discussion, even if you are unsure about the oscillators.

yes, although I'm not sure if the sparkiness was noticed previously.

The monomer would be even sparkier, and the spark is more accessible, if you can supply a P18 diagonally-accessible bit, domino, or duoplet spark; unfortunately P6 and P9 don't work directly

p6 sort of works, as noted here, but the p6 interacts with the resulting spark and makes it inaccessible.

Most of this probably isn't interesting — there's a smaller turning toads stabilization and a possibly reduced dimerization of a known weak-ish sparker/LWSS-to-G (I haven't checked the known version), but that's it for now.

These are just trivial p3 sparker variants, just for record's sake.
x = 50, y = 24, rule = B3/S23
