At the risk of being over-commercial in a posting here, it sounds as if you might be best advised to send both shifters to us and we can have a look for you.
Normally the 4mm head bolts will move readily enough - it may be that:
the central securing bolt in shifter #1 had been replaced with a Torx head bolt from a Record lever at some point (they are interchangeable) but using a (normally 3mm) key may have damaged the socket ...
you have a very old Chorus unit in which the central securing bolt is LH threaded - in that case it will be a 4mm allen-key headed bolt.
If trying to rotate the allen bolt in your Veloce unit caused the return spring to "unhook" from the body, it was incorrectly fitted in the 1st place - the lever will still have worked but the action will have tended to be heavy.
We can correct any / all of the above problems.
Best PM me, or drop a mail via our website to organise if you'd like us to help.
