https://blockchain.info/en/address/1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a is most likely a mtgox wallet
here is why:

start from here:

https://blockchain.info/en/address/1LNWw6yCxkUmkhArb2Nf2MPw6vG7u5WG7q .. this is a known mtgox wallet

436K moved to https://blockchain.info/en/address/1Cj5kAeGK5CQSubY1Bk6HbGdweq15eJtH9 ..still a mtgox wallet, in fact 279.15294827 BTC is a withdrawal from one of the user in the leaked db

76b04b58-c333-44cd-a322-459fc0956800,647e689d-c56b-407a-a405-58a45b315af9,"2011-12-06 21:44:27",withdraw,-279.15294827

now let's follow 435,960.99837219 BTC

https://blockchain.info/en/address/1KNY4rzu5qDaLeqwBx4Rq9BWiDkNciUzkX ..still mtgox and you see another withdrawal (350BTC)

bb53da20-bc36-4776-894e-2d90b4946b62,d5c357fc-bade-43b7-9887-06cf1ea0daba,"2011-12-06 23:25:23",withdraw,-350

then follow 435,686.26054584 BTC and you will see another withdrawal, and again and again...
until you get here:

https://blockchain.info/eb/address/1M1ZkWpHfuQthji2AVsGDvpfY2PrcXQar6

then the wallet is split in 2 big wallets, follow the 202K one and then after several other splits you end up here:

https://blockchain.info/address/1Gwi7JFpSZfemLuPWJ8zqBsRNx8GnxVjGA

with 1K going to the 1933 address and the rest being used for other withdrawals

it's very likely the the 1933 address belongs to mtgox

so you think 1933 belongs to gox?

So how many coins do you think mtgox have (or maybe lost keys for) altogether?
Do the 436K you refer to includes the known 200k?
