I think you are correct

however, I don't see the bucket anymore.
Davis Instruments (the one in Hayward CA, because there is another one)
seems to develop unusual products, many of which don't stay on the market
for long. I have an anchor chain brush (wraps around the chain) from davis
that is no longer available.

the top cut back doesn't?

Davis (I think) made a 2 gallon cleaning bucket where the bottom was a
flap that opened inward. It was really an "un-bailing" bucket, because
you could drop it overboard (attached with a rope, of course) and easily
fill it with sea water.
