Only joking regarding "not fitting the descriptions" - it's a useful excuse I can use when I can't identify something ;)
I use Poulain and also Ing (which has a good key but not good illustrations). Nannenga-Bremekamp's book looks very good. I don't have a copy - it's quite expensive but looks like it could be worth the investment.
Your collections are fantastic. Unfortunately I have quite a few other responsibilities at the moment which mean I am in the field less than I would like.
