Can anyone help me in identifying who the manufacturer of this frost free faucet is?

I am needing to repair the faucet but have read that every one is just a little different, making a simple repair kit from the hardware store very hit-or-miss.

Looks like it's made by Mueller Industries

Maybe an older QuarterMaster brass Anti siphon frost free sillcock?

    Awesome. Certainly looks right. Now the hunt is on for parts! Thanks! Commented Apr 7, 2016 at 0:32
  • FYI Mueller / B&K has a guide for identifying their sillcocks that I found helpful: bkproducts.com/wp-content/uploads/… Page 7 also talks about a design flaw that causes a leak at the handle. Also see the question on page 10 "Why does plugging the pinhole fix the handle leak?" that says, "Replacing the stem will also fix this leak." Commented Nov 11, 2022 at 2:49
