Gearbox number

[vlust]

Hi,
On the underside of the gearbox I noticed on two different places the same number that I do not understand. The number is "10D59" My car was built in 1959(Healey 3000 Mk.1)
Can anyone help me to explain this number?
regards,
Victor

Just a wild guess, but if your car is a 1959 3000 MK1 maybe the numbers mean the following. 1=MK1, OD=Overdrive, 59=1959.

G’day Victor, As a 100 owner I’m not too well versed on details of the later models but what BN6 has suggested makes sense on the face of it, except that the first 3000 model would only have become the “MkI” when the MkII was introduced. Just as the 100 only became known as 100/4 when the 100-Six came along.
Cheers,
Alwyn

Side note: A bit of teflon thread sealant on the plug might stop that leak (does for my cars).

Could be a date code. German cars have lots of parts with date codes stamped on them. 10th day of April (D) of 1959

Thanks for all the suggetions. The date code seems to me the most likely explanation since my car was produced in May 1959 according to the heritage certificate. So April 1959 would fitt into that explanation.
I will certainly follow up on the tip of the Teflon tape.

I will certainly follow up on the tip of the Teflon tape.

The paste that's sold in tubes for natural gas fittings (PFTE, maybe?) Is gasoline and oil resistant. Easier to apply and more likely to stay in place than the tape.
