The post-war 31– range of Swans is often deprecated because of the small size of the nib. Quite strange really, because the Swan No 1 is no smaller than many nibs that meet with approval, such as the bulk of the medium to lower-cost Conway Stewarts but I have seen people say that they avoid them because of their quality. In truth, the build quality of the pen is same as that of its bigger siblings and the fact that so many of them have survived in very good condition supports that.
Judging by the very good condition of the gold plating, this 3160 hasn’t seen much use. The plastic, too, has much less in the way of marks of everyday use than you would expect to see in a pen of this age.

It expands easily from fine to triple broad and the snap-back to its usual shape is instant. The ladder feed supplies enough ink to meet the demands the nib makes. I had some fun testing this pen after re-saccing. Here’s a writing sample to give an idea of its capabilities:
