Quoted from Starscream:
Yeah looking further into it I'm not too sure?
The only thing out of the ordinary are the pop bumper plugs, Which are factory,
But no green lock, or white clockface, But the white operating manual threw me for a loop
Serial number is 53320 110361
I thought it was the last 3 digits but I don't think they were built in order like that, I don't believe the next one after mine would be xxx362
I have read that they put the extra posts in with tz when they sent it out to the operator. They let them decide if they wanted to put them in or not .so maybe they were put in and then taken out when put into home use and plugged .
