Serial number is on the frame.
The serial number goes beyond published data. You will need to call Colt.
All Australian banknotes have a serial number. For each issue of banknotes, there will be a first and last serial number. The Australian paper Fifty Dollar note issued in 1973 with the signatories Phillips/Wheeler, had a first serial number of YAA 000000. The last note printed in that series had a serial number of YAU 999999. The next series of Australian paper Fifty Dollar note issued in 1976 with the signatories Knight/Wheeler, had a first serial number of YAV 000000. The last note printed in that series had a serial number of YBX 999999. Banknotes with first and last serial numbers usually have a higher collector value.
The serial number by itself doesn't identify a specific model.
Nothing special.
