Webley manufacture date

[Troubledshooter]

Hi all
I wonder if anyone can put a age and model to the following:

Webley Vulcan serial number 026461 - December 1975 ?

2 x webley trackers serial numbers:

20080 - January 1986

22563 - January 1987

Any info greatfully received.

Kind regards

The above dates are taken from incomplete Webley records, and the serial number for the Vulcan is not marked a such, just listed earlier on the same page as the Trackers etc. which are marked as such.
Hope this helps.
