This is a 901 transmission from what I can tell. The 901 was used up until 1972, and the model you have (if original) is a magnesium housing 1969-1971. SOURCE: Bruce Anderson's performance handbook, pg 226-227.

According to my factory spec book listing serial number ranges for different gearboxes this is a Type 902/1 gearbox; ratios A-F-M-S-X with 7:31 Regular R&P, it was used in 911 and 911L in 1968. This should have a cast aluminum case.
If I read my spec books correctly the MY 1971 gearboxs have first 3 digits in numbering as 711 or 771 for the 5 speed boxes. These have cast magnesium case. Hope this helps <img src="graemlins/yltype.gif" border="0" alt="[typing]" /> <img src="graemlins/burnout.gif" border="0" alt="[burnout]" />
