I just picked up an Eden WT-550 for dirt cheap. Haven't tested it yet, but seller seemed like an honest chap. Anyway....there is no serial number or model number on the back panel, says output is 400w into 4ohms and there is no Min Load number.

These are all stats I don't really care about, but does this seem odd? Dumb paranoia, but I don't trust anyone especially since it was a stupid good deal.

May have been a European sample, pre-production, early production or something like that. I would also assume it’s 4 ohms minimum load.

A picture of the inside might shed some more light on what’s up.

It does say 4 ohm on the right side. I wouldn't push it under that till you know for sure. (Which I'm sure you wouldn't).
The minimum ohm rating likely faded out over time.
Eden was known to change things up over the years. Especially on platform changes. They offered "upgrades" on certain heads.
congratulations! I haven't heard a bad one yet.
Edit to say....
Was gonna say Rip or someone knowledgeable on those heads will be around shortly.

The Eden factory upgrades were primarily WT-300 => WT-400, and WT-500/600 => WT-800 power section. Don't recall a WT-300/400 => WT-550 upgrade ever being offered, though there may have been a few made like that (?). Should be easy to determine what it is with the top removed.

It's common to find hand-built tube amps and other electrical equipment with their S/N's, Model #'s, Build Date, hand written on the back panel with a pen or marker. Over the years the ink will fade out or literally cleaned off the panel. Sometimes you can see the indented lines that remain if it was written on a foil stick on label. This type of info should be stamped into the metal rather than simply hand written with ink.

This. My trace GP11 w/ unknown amp section has very faded sharpie serial numbers.
Or it was never there to begin with as agedhorse says
May have been removed, but no way of telling, and this looks clean. My vote says never there

I've owned several World Tour heads. All the info was written on the back with a Sharpie and would fade or rub off over time. Not uncommon. The 400 watts @ 4 ohms looks like it was written by someone with the wrong type of pen. Also, everything I've read says the WT550s are stable to 2 ohms even if marked 4 ohms minimum. Check out the Eden club for valuable information. Great sounding amp. Enjoy!

Generally the sharpie stain will remain in those white areas. Since the other legends remained, I don’t think this was a retail production unit.
