Real offset of End Header in example archive = 0x20 + 0x0E59 = 0x0E79 20: 00 21 16 89 ... - start of compressed data. Note: if the file was compressed with LZMA method, the first byte is always 00. If first byte is not 00, then archive uses another method (it can be LZMA2 or encrypted data with AES).
