Thanks for showing the photos of these very nice Strathearn weights. And well done for perservering with the links.
Both weights would look very nice in my collection - so if you get bored with them and fancy sending me a gift ...
These are shown in the 1979 brochure as:
"PSFS102" - Top and side facets and quatrefoil garland within regular garland.
"PPS101" - Top and single side facet, to stand upright, hence the "Portrait" designation that Richard mentioned previously.
In my view, all of the 1979 range of weights were really good and show what could have become regular best sellers if they had continued the paperweight production.
