Look at these two. Pretty much everything that is wrong with 4mm scale whitemetal figures. The bloke especially has some "interesting" proportions - the photo actually makes him look better than he is!
Both were found at the bottom of my figure box when searching for seated people to populate a tramcar. For this role, they will do the job perfectly. You can't see them properly through the windows, but you will be able to see that there is a figure in there. Hence my perfunctory efforts at painting. No need to spend lots of time, or use highly detailed (read: expensive) miniature people.
And it's better than throwing them away.
