Today I received, from China courtesy of evil-bay, 100 HO (1/87) seated figures and 100 OO (1/72) mixed seated and standing figures.
The HO figures have a nice selection of different mouldings and I will use them if they do not prove to appear too small. The OO figures have a number of different standing figure moulds but only one seated mould. However, if I need to I should be able to do some surgery and transplant different upper bodies onto seated legs.
