Separate complex text from number patterns from a single string

I have a text file that looks something like this (but with hundreds of lines):

1147-1 SYRUP: DR.PEPPER 5GALLON/BOX

1653-1 SYRUP: DIET DR.PEPPER 5GAL/BOX

2011-2 WATER DISTILLED 6 / 1 GA

1217-2 ALL PURPOSE RASPBERRY FIL 40#

1273-1 STRAWBERRY PIE FILLING 38#

2893-1 BREAD: SOURDOUGH 12/1# OVAL

2287-1 BREAD SQUAW: 8/2.25#LF

1929-1 VINEGAR HERB CONT GRDN 12/12.7

1949-2 KETCHUP: 16/14OZ-PLASTIC BTLS

2408-1 CONE 3 NAB SAMPLER 28/45

2939-1 DULCE LECH FLVR PKT 3/12 EA CS

3017-1 GINGRBRD FLVR PKT 3/12 EA CS

3055-2 EGGNOG FLVR PKT 3/12 EA CS

3192-1 ORIGINAL MRS. DASH SEASONING

I've created the code to pull everything in from the text file line by line and strip out the numbers at the beginning and save the next portion (ie SYRUP: DR.PEPPER 5GALLON/BOX, ALL PURPOSE RASPBERRY FIL 40#) to Mid(nextLine, 10, 30). I want to take that portion and split it up by pulling the name (SYRUP: DR.PEPPER, ALL PURPOSE RASPBERRY FIL), the size (5GALLON, 40#) the number of that size (if it is 12/1# = 12x 1LB) and the unit (BOX, LB) out. As you can see almost every line is different but with many similarities. Not really sure what to do next. I have been trying to use re.Pattern = "GALLON|BOX|#|LF|GAL|EA|CS|BTLS" to pull out the unit portion but I don't know what else to do, so any help would be greatly appreciated!
