How to select a string between two strings in a column in SQL Server?

I want to get the string between two strings in a column of a table. How can I select the column? I have written the strings which are on either side. Can anyone help me how to include the column name with the string here?

DECLARE @Text NVARCHAR(MAX)

SELECT 
    SUBSTRING(@Text, CHARINDEX('Manufacturer Name : ', @Text), 
                     CHARINDEX('Manufacturer Part',@text) - CHARINDEX('Manufacturer Name : ', @Text) + LEN('Manufacturer Part')) 
FROM 
    tbIMPACArchiveNew 
WHERE 
    (Description LIKE '%Manufacturer Name: %' 
     OR Description LIKE '%Manufacturer Name : %') 
    AND Description LIKE '%Manufacturer Part%' 

Expected result:

Column A                                                       Expected result
