Barrel markings interpretation ?

[Pukka Bundook]

Again, a Very helpful reply Fernando!

I believe you are right; That Laborde did not make the barrels. Most gunsmiths bought in their barrels and I see this as most likely in this case.
If Spanish barrels were selling at a premium, as indeed they were, I do not suppose he had any great worries regarding supplying what was in demand. :-)
That is a very beautiful pistol you show!

Very nice work. The cocks are very interesting, as we think of them as later than Laborde was working. The trigger-guard is the same 'pillar ' type as on the gun in the opening post. Not exact, but same style.
I will attach further photos as soon as possible.

Kind regards,
Richard.
