Even at first position, I need to stretch quite abit for the 4th finger to be in tune and I am not able to reach from low 2nd finger to 4th. I do have problems with reaching G string even in 3rd positions. My hand goes around the neck when I do. I did not pursue the 7/8th size instrument because I have a feeling that these instruments are very rare in Singapore.
The problem you have described here is exactly the same as I have with a full sized violin. The only other option that may be more viable in Singapore is to find a full-sized violin with either a very slim neck and/or a shorter string length, ie. the length of the string between the nut at the far end of the fingerboard and the bridge. On average, the string length on a full-sized instrument will be about 328 mm, but it's possible to track down old English or German violins with string lengths 4 or 5 mm shorter. This may not sound like a huge amount, but it makes a big difference to the stretch between the notes - especially for the fourth finger. The violin I play has a (smallish) body length of 349 mm and a string length of 324 mm. It's an English violin dating from around 1830.
Depending on the position of the notches on the edges of the soundholes it might be possible to have the bridge moved so as to shorten the string length on you exisiting instrument. You would need to discuss this with a good luthier so that the general setup of the instrument remains unchanged as far as tonal qualities are concerned.
If your brother wishes to send pictures of the current shoulder rest/chin rest setup then that's fine with me.
