The analyses of a text #2

The narrator recalls his adolescence.
He was an apprentice for Mr. Spenlow.
He and Mr. Spenlow's only daughter Dora fell in love with each other, but after Mr. Spenlow's sudden death, she moved in with her two aunts and confined herself there.
He made an appointment with Dora's aunts to visit them through correspondence and came Dora's aunts' house with his best friend Traddles.
Miss Lavinia and Clarissa are Dora's aunts; Miss Lavinia, the younger one took the lead in this conversation.

Miss Lavinia turned my letter, so as to bring the superscription towards herself, and referred through her eye-glass to some orderly-looking notes she had made on that part of it.
'It seems to us,' said she, 'prudent, Mr. Traddles, to bring these feelings to the test of our own observation. At present we know nothing of them, and are not in a situation to judge how much reality there may be in them. Therefore we are inclined so far to accede to Mr. Copperfield's proposal, as to admit his visits here.'
'I shall never, dear ladies,' I exclaimed, relieved of an immense load of apprehension, 'forget your kindness!'
'But,' pursued Miss Lavinia, - 'but, we would prefer to regard those visits, Mr. Traddles, as made, at present, to us. We must guard ourselves from recognizing any positive engagement between Mr. Copperfield and our niece, until we have had an opportunity -'
[David Copperfield by Charles Dickens]
1. I'd like to know why it is "Mr. Traddles, to bring these feelings to the test of our own observation,"not "Mr. Traddles, brought these feelings to the test of our own observation."
2. I'd like to know if "so far" means "to this extent."
3. And I'd like to know "as made" is the objective complement of "regard."
Thank you in advance for your help.
