In case the first partition was encrypted, you won't stand a chance in
restoring it, since the first partition starts on sector 2048 (1MByte
from the bstart of the device). For obvious reasons the header would be
gone and certainly some important parts of the FS.
If your encrypted partition was 8,17, as your data suggests, then the
first partition was encrypted and is thus severly damaged. (sdb1)
So, if you do not have a header backup of the drives masterkey at hand,
then this is a goner.

Hi,
I've accidentally overwritten the first 1.1 GB of my external hard drive
with dd. As far as I remember the drive contained two partitions from
which one was encrypted with LUKS. I'm not sure if the encrypted one was
the first or the second one...
I dumped the hole disc with ddrescue.
I was able to extract the following from my laptop:
luks-afe73a24-e4ab-4d49-90b9-119da11bc7c6: 0 5860526990 crypt
aes-xts-plain64 [key (don't want to share it in this mail)] 0 8:17 4096
Is there any possibility to restore anything of the encrypted data?
Thank you in advance!
Oskar
