Our Edison Gem Phonograph - a couple of questions

[cm]

Hello All, newby here!

I'm hoping to get my wife's (UK) Edison Gem working (Number 20362). She remembers it being in her parent's home from when she was a child. At some point the silver (aluminium?) horn was lost and the machine was left to gather dust for many years.
I've given it a good clean including removing quite a bit of rust and am pleased to report that the motor runs sweet, although I've yet to obtain a drive belt. The problems I can see are:
1. The mandrel shaft collar (I think that's  what it is called!) is missing it's grub screw. Can anyone tell me what the thread size is and advise on a replacement?
2. The four base-plate to case retaining thumb-screws are missing. Again, can anyone tell me what the thread size is and advise on a replacement?
3.  Am I right that it would have had a 14" horn and that one of the readily available reproductions (in nickel) would be a direct fit?
4. I've yet to work out what I need to do to the reproducer.
5. Part of the winder has broken off (so there is no longer a 'slot' in the end), but it still works. 

I've attached several photographs including photos of the collar and base-plate screws and would welcome any comments.

Thanks.

Chris

Might I suggest you also post this on the Talking Machine Forum (TMF)? They have a section there specifically devoted to British and European machines; that site tends to be much more active as well (not that there's anything wrong with *this* one) :-)
