Galvanized piping is a disaster waiting to happen. IT tends to rust from the inside out.

You can't buy a drum trap like that any more the metal baffles tend to rust out, and then it doesn't work as a trap anymore. You can buy a drum trap that meets code, but it's generally not a good idea. It is impossible to snake a clog out of a drum trap. Some of them can be taken apart, but you risk ruining an old one in the process.

Drum traps NEVER had "baffles". There are NO "drum traps" that meet code. You snake a drum trap by removing the cover, which is why they have the cover in the first place. There is no way to "take a drum trap apart". Other than that your reply is correct.

A drum trap, to some, looks nicer when exposed than a p-trap and can take up less space, but you cannot snake one to remove a clog. I had to look up how a drum trap was made - I was wrong, as pointed out...essentially, it's a barrel/drum, with the inlet near the bottom, and the outlet near the top that traps enough water to create the seal required. The original thought on their use was that it would trap things and not flush a solid out (say a ring, or piece or jewelry) whereas, a p-trap might allow it to continue on into the main sewer. At least, that's what one website professes. Today, almost all traps are p-traps. A p-trap will tend to stay cleaner and generally, a snake can go through it.

A Drum trap, A S trap, A Running trap are all illegal these days, but what they have in common with a P trap is they
keep Sewer Gas, IE Methane Gas and Bacteria from coming back inside the residence making people SICK !

Cut Out and Replace with a P trap you may need a Plumber to Reconfigure the pipes correctly,
as long as that drum trap remains open you get the aforementioned GASES and Bacteria leaking
into your House

codewise, bottle traps are also illegal, because they depend on a concealed baffle to maintain the trap seal. The baffle can erode, or come loose without any outward indications of the failure.
