how old is this c8

i just picked up a black tube celestron c8 ota.
i am trying to figure out how old it is.
is has special coatings, not starbright.
there is an orange cap over the collimation screws.
the serial number is 828483.
i spoke with celestron, tech support said they cant tell
the age from the serial number which i found odd.
any help??
didnt come with the stock dovetail.
it looks like the sp-c8 or classic c8.
i am guessing mid 80's

I am guessing around 1986 to around maybe 93 with the orange cap. I just bought a late 80's C6 , but it does not have the orange center. My lens cover has the orange center.
