Merging Multiple Data Cells Into One Cell?

I have a spreadsheet where I am trying to add up codes and quantitys, after this I want the repeated info deleted. For example;

12.004RWHB 4 Row Wooden Handle Welders Brush
12.004RWHB 4 Row Wooden Handle Welders Brush
20.004RWHB 4 Row Wooden Handle Welders Brush
24.004RWHB 4 Row Wooden Handle Welders Brush
4.004RWHBSS4 Row Wooden Handle Welders Brush S/S
10.004RWHBSS4 Row Wooden Handle Welders Brush S/S
12.004RWHBSS4 Row Wooden Handle Welders Brush S/S

So what I want to do is add the numbers up so I can get one value. For example, 4RWHB I want to add them all up so that it totals 68 still shows the code and description but then only shows 68 4RWHB 4 Row Wooden Handle Welders Brush and not the same line repeated. I want to condense all the information down so where there is same model numbers I can add it up and it doesn't give me multiples but summarises it down into one line per model number.
