What does this symbol stand for on a drawing?
Just kidding ... never seen before !
I have a good background with GD&T however I have not seen that one before. This website lists the symbols and explains the use.

I did not see in it there, is this a finish grade symbol?
It could be a leaderless and sideways weld symbol (or an attempt to draw one without knowing what elements mean). Beyond that, this looks to be more like a redline/proofreading symbol for literature. Was this used on a mechanical drawing?
I can't figure out how to reply with another photo so I'll email it to you
Old style finish mark.
J. Mather Yes, ƒ was typically used before 63 µ in. finish (mill) came into being. (or 32µ in. for G)
As J. Mather stated it is the old symbol for "Finish This Surface".During my apprenticeship a few years (OK, decades) ago, I was told it was a hangover from the symbol used for "Fettle" as related to removing the flash from castings.
EDIT: Just had a flash back memory (déjà vu all over again ?)
hey I was close, a finish symbol.
Do they have anything that shows the archive of gd&t symbols?
I still have my gd&t book from school , however it only shows the current standards.
Hey Kelvin Lamport It's good to have these skills under our belts! Old School is the best school...well, most of the time Besides, we're closer to retirement...
looks like a bit skewed swastika - at least to me. - not sure if that's good or bad.
Back in my drawing board days (or the Dark Ages as I call them), this symbol was used as a generic finish mark. On really old mechanical drawings, the symbol will look almost like a lowercase cursive "f".
the "f" symbol I remeber
finish mark means: machine (mill) surface rather than leaving "as cast"
Yep, that's my vote: called a 'finish symbol'.

Yes, it's a finish symbol. My technical drawing text book from 1974 even calls it "old style".
I probably used the same book...
Thank you all for the help!
