Hi Elliott,
Sorry, I'm not familiar with the workings of those guns, but you can get good diagrams for them from Chambers: http://www.gunspares.co.uk/shopdispl...ana%2FOriginal
I use a pot of Bisley gun grease for springs, but I think I've used a product called Abbey LT2(?) before as well. don't go mad with it though
There is a great thread on tuning spring guns here:
