Failure of comparison of valid pub key's .asc files

[J B]

Hi,

My system is Arch linux.
Linux myhost 4.4.1-2-ARCH #1 SMP PREEMPT Wed Feb 3 13:12:33 UTC 2016 x86_64
GNU/Linux
gnupg 2.1.11-1
gpgme 1.6.0-2
libgpg-error 1.21-1

I have a problem with comparing contents of publick key ascii files from two
sources:

1. downloaded from web page .asc file
$ cat 0xC65285EC.asc

Note the difference in output from 'gpg --check-sigs C65285EC':

case 1.
gpg: 1 signature not checked due to a missing key

case 2.
gpg: 2 signatures not checked due to missing keys

Both .asc files represent the same public key, and when imported into gpg,
correctly verify a signed app executable.
But when I compare them, they differ:
$ diff 0xC65285EC.asc 0xC65285EC-key-server.asc
10c10,12
< d2luZUBwcm90b25tYWlsLmNvbT6JATcEEwEIACEFAlUGFsQCGwMFCwkIBwIGFQgJ

$

Where is the problem ?
The --export option to .asc entry ?
The --import option from key server entry ?
Something about the key stored on key servers (I imported it from two
servers
with the same result) ?
Anything else ?

Thanks,
jb
