Here are some I have inherited from my grandmothers.
Tea always meant bridge rolls with cucumber, egg and cress; wafer-thin bread and butter; toasted tea-cakes with apricot jam; 'fancy' shop-bought iced cakes; and tinned fruit with evaporated milk or a wobbly, pink rabbit made from Symington's Table Cream. The bone china cups are unmarked but my grandfather's large extended family lived in Stoke-on-Trent, so it's very likely it was a wedding present in the 1920s and came from one of the famous potteries.
The hand-painted 'cherry' cups were from my maternal grandmother's second-best crockery collection, which included a dinner service too. Made by Barker Brothers/Tudor Ware in creamy stoneware, this was a popular design of the time, which my grandmother collected for her 'bottom drawer' during her long engagement in the 1920s. I think they were bought from Boots or Timothy White's (possibly Woolworths) in Basingstoke.
Tea time at Grannie's was always thick slices of home-cooked ham with salad from the garden; home-made scones and strawberry jam; home-baked fruit cake and Victoria sponge and sometimes a lardy cake or some giant macaroons from the baker's. With Grannie's special treacle tart and custard to finish off with, it's a wonder any of us could lever ourselves from our chairs afterwards.
I've added to this set over the years at boot-sales and from eBay and until recently (when the attrition rate began to seem unsustainable for such a vintage range) it has been in everyday use here, too.
