Hmmm - you are really asking two separate questions and an accurate answer to either one depends on more information than contained in the sample.
Your first question is whether the handwriting is within the appropriate range for a very bright verbal boy. However, graphomotor ability is not related to verbal cognitive ability so the question is really whether this handwriting sample is typical of fall first grade. I would say that it looks low average to me if that was a concerted final effort and high average if it was a quick rough draft.
Your second question is whether the substantive writing is within the appropriate range for a very bright verbal boy. However, output requires more than input so even in the absence of 2E, that range is extremely wide. I would say that particular sample would not suggest high verbal ability to me, but I would not be shocked either if I were told that the writer is a verbally gifted first grader.
