colt # on Ltwt Sporter

[p7fl]

I've had a Colt Ltwt Sporter since 1993.
There is no # on it. I am the 2nd owner and it did not come with a box.
Looking at the list on Wiki I've always thought it was a 6520 but after reading other threads on the 6520 I am not sure where the Sporter's fit it.

Anyone know the correct #.
Just curious
TIA
