I don't know if the metal bailers are even made any more. The last two I installed were plastic and came from D&R Marine. They're expensive, about $40. But they are easy to install, and it's easy to clean algae off of them after the season. The bedding turns out not to be that critical. The O-ring seals are what keeps the water out. I've had a couple of people recommend wiping the O-rings with light grease to ensure a seal.
The outer shell of the bailer does not fit precisely against the hull, and D&R recommends filling that space with silicone. The silicone doesn't actually affect the seal. It's mainly to create a smooth profile and prevent dirt and marine growth between the bailer and the hull.
By the way, even the O-ring seals aren't mission-critical. The bailer on my boat (1973) fits into a solid tube that bridges the space between the inner and outer hulls. If you should, for instance, not listen to your wife's advice on approaching a dock, overshoot the end, crash the boat into the breakwater, and shear the entire bailer off the boat, you can still sail back across the lake without sinking. I know this for a fact.
