Ok, curious photo of the day is...
Main shaft blocks have what looks like -2 on them, also mismatched in colour (not anodized I assume), maybe the belt rubbing, or lack of side brace in question, so are they tweaking the position of the shaft in final testing, hence the -2 marking???.
Ok I'm bored, but did find the picture interesting, I just want them to finish the EC and ship out something I can buy already...
