Tranny stamp

[Bob Claffie]

While checking tyhe numbers on my new 100/6 today came up with a strange one. The small circular stamp on the top of the transmission read "BN4" but a "7" was over stamped in a larger font. I know this isn't the original box for my car but am curious if B/L used left over castings and marked them thusly? (I do have the original transmission but in a hundred pieces). Bob

Bob, My 62 bn7 also has a round tag with bn4 looks like it's stamped out from the bottem side with a 7 stamped in over the 4. It also has a manufacture date of sometime in 1960 but it must be located on the bottem because I seen it before the transmission was installed but since it's in the car now I can't find it. I do have the tunnel cover off and can view the round tag. I belive this is the original transmmission for my car and I belive they used what ever spare parts that were in stock to meet production. Mine has the side shift no overdrive.Bob

This gets stranger as it goes. My tranny with the "7" overstamped is S/N B11930 and my "spare" which I thought was the original does NOT have the seven over stamped but it has a LATER S/N B12330. I agree that the workers just grabbed whatever was closest. Both the above transmissions have OD. If these two transmissiona are exactly 400 apart what would that relate to in production time, three or four weeks? Bob
