Will this fit a Benjamin Trail NP Nitro Piston?
No it will not
Will this fit my 1980's Beeman 250, I think it is the same as a Diana 45?
You would need to confirm that the 250 is in fact the same and that it has the elevated dovetail rail on it. If it does, you should be okay.
Will this work with an older RWS 34? My trigger has a 2 screw adjustment, which I believe is a T01.
I would go with the Hawke Adjustable Base instead for the T01 models. http://www.pyramydair.com/s/a/Hawke_Sport_Optics_1_Pc_Elevation_Adapter_3_8_to_Weaver_Rail/4163
I have an older Diana 48/52 (11/87). Will this mount fit?
The description says this item will not work with the RWS 34 with the new T06 trigger. Is there a drooper scope rail that works with RWS 34s that have the new T06 triggers?

Please what are the best scope rings for this UTG scope mount base?
I would recommend Leapers/UTG weaver / Picatinny rings for this base. You would need to select the model appropriate for your scope tube diameter and objective size.

You would want MNT-DNT06 [UTG Drooper Scope Rail, 11mm-to-Weaver...]

Take a look at UTG Drooper Scope Rail, 11mm-to-Weaver...
Should I use locktite - Blue when I mount this base to my RWS34?
You can use the blue locktite, but only if it moves.
