Hello. I purchased a 30-40 Craig a few months ago and I am curious as to what exactly it is. From what research I have done it was made in 1903 and has what I think is a 1902 rear sight. Front site is missing the blade. It has a 30" barrel measured from the bolt face to muzzle. I believe the stock is a shortened rifle but I'm not sure. It has two cartouche one is the typical above trigger guard on the left side I think it says 1896 or 1898 can't make out the last number( I believe the stock was refinished) there is also a cartouche 3/4" behind the trigger guard but I can't make it out. I will include pictures and would like as much help as possible.  I measured the muzzle and it came out to .625" I read somewhere that this can help determine exactly what it is.
