Why do you think the attachment is split into 14 parts?

You could write $msg->as_string to a log file to see if the attachment is split into 14 parts at that point or some time later in processing. On Debian Linux, MIME::Lite does not split an attachment into multiple parts given arguments similar to what you are using:

use strict;
use warnings;
use MIME::Lite;

my $msg = MIME::Lite->new(
    From    => 'mail',
    To      => 'mail',
    Subject => 'Perl Test',
    Type    => 'multipart/signed',
);

$msg->attach(
    Type    => 'application/msword',
    Path    => 'test.doc',
    Filename    => 'FORM50.doc',
    Disposition => 'attachment',
);

print $msg->as_string . "\n";

Maybe the attachment is being split at the receiving end of the communication? How are you receiving the email and saving the attachment?
