Thanks for posting this query John and for identifying the pistols, which I'll add to the catalogue thread.
I'm not sure either which models Burgo sold as its own, apart from the smallest and largest models, which are more distinctive. I can't see any Dianas in there apart from the smaller guns (16, 23). I think BSFs are there too.
I wonder if some of the smaller rifles are Haenels, somehow brought across the wall-less border and resold in the West? There would have been plenty of profit to be made there.
The Burgo pics of which John M has posted doesn't seem quite to match any of the illustrations in this catalogue, as far as I can see.
I think the Weihrauch's are as follows, with the identification made partly by looking at the illustrations in the AKAH catalogues I've just posted
here. Something I realised when you pointed out that these were drawings was that the artist has clearly made some errors and was probably working from photos.
His portrayal of what look like HW35s lack the stock cut-out for the barrel lock lever, although the (rather small) lock lever is present. I don't think he had a clue what it was. The HW35 rearsights are done badly too.

Edit: Interestingly, this catalogue lists makes, models and prices also sold by Burgo but marked under their own brand. Maybe that provides a clue as to which rifles Burgo was bringing in, although clearly a lot of them are missing from the Burgo line up:
