that was the address who sent the BTC. There are lots of other strings of numbers etc but dont know which is the tx ID - dont want to post something if im not ment to!!?
I understand your concern. It can be dangerous to start giving information to strangers on the internet if you aren't sure what information can be used to hack or steal bitcoins.
It looks like that address has been in use since 2013-11-14
The most recent transaction with that address would be 2014-02-26 09:16:36 UTC when they sent 0.1 BTC to 1BAJ1dk6zs3zDnUzzNCGkbPbrHXzqo1R8a and it looks like that transaction probably sent 0.141 BTC in change to 1PsJqpaWB4HutM2XxsL1JMgg1fieo7Qi7D (it's possible that I have the change output and the receiving output swapped).
I'm guessing one of those two are the output you received. If so, then the transactionID is
3c461e97a32708a49815f0dacbae32e6cc7f893f042fc24b262e83b38dcb8f5d.
Prior to that, the next most recent transaction sent using bitcoins that were received at 1CsdwuSV6vnMM8Bv4ngMS5aWf5zAUhjF4k looks like it was probably 2014-02-21 11:25:22 UTC. That transaction appears to have sent 1 BTC to 1MvaQ3Lr86Y1ShmicbP5DefLH81cHhFm4q.
I don't see any obvious indications as to who might own 1CsdwuSV6vnMM8Bv4ngMS5aWf5zAUhjF4k. You can see some of the other transactions that they've sent and/or received at the following link:
https://blockchain.info/address/1CsdwuSV6vnMM8Bv4ngMS5aWf5zAUhjF4kIt looks like they sent bitcoins to 1MvVfW9UofyqAHd8VG7taWJ5KWYxksC8F7 multiple times.
There don't seem to be enough payments for it to be a "faucet", pay per click, or other "free bitcoin" type site. It doesn't appear to be a mining pool either. If I find time to look into it a bit closer later, I'll let you know if I figure anything out.
