Well,
It seems that so far 3 different variations of Portuguese lanyards have been identified.
The first type is the one that Jerry has faithfully reproduced (short leather tab and 2 leather sliders).
The second type has a slightly longer leather tab and uses leather sliders that are made from punched through flat pieces of leather. These pieces cannot be removed from the sling and easily break. Many have probably been replaced in Portugal by the tan colored leather sliders of the first type.
The third type has the bayonet hook connector, which is fastend to the pistol by using a separate lanyard ring: the ring is attached to the pistol's lanyard loop and the lanyard's bayonet hook attaches to the ring.
Tan leather usually seems to indicate a repair. I have studied quite a lot of Portuguese holsters and have a couple of Portuguese lanyards here. The tan color of the sliders matches that of period repairs on one of the holsters perfectly. It also shows that a repaired, beat up old holster can sometimes be of more use than a minty one
