need some help with equipment connections

Hello all,

 

I recently purchased a Chromatography Reservoir Flask that has a 70mm (?) thread adapter on the bottom (on the outside of of the 50/40 spout), and a 50/40 (?) on top. I've measured the best I could, however, if these numbers aren't standard then I'm wrong.

 

I would like to attach a flat bottom flask to the bottom, preferably using the threaded adapter, but not essential.

 

As well, some sort of cap for the top that will allow me to connect to a distilling tube then to a west condenser (20/40).

 

These large-mouths are giving me a hard time in terms of finding reducers/adapters.

 

Thanks for any help.
