How do we date series parts?

**digger** · 19th May 2013, 11:14 AM

Start with this!

Who can guess what this is ?(should be easy!)(trying to keep thread interesting!)

Interested to hear what numbers etc indicate what dates on different ones.

For instance I have this with "LK51 32 rb1-2" or it maybe "LK51 32 pb1-2"
I assume this is a 1951 part (its on a '52 80") -But wondered how accurate this would be across the board with these parts etc

anyway interested to hear how to date them (all makes) if someone knows.

and other than the obvious (eg date plate on radiator) how do we date other parts? (and examples please)

Cheers

L= Produced in London
K= 11th letter of the alphabet =11th month = November
51=1951

Thanks BSF! obviously my attempt to be cryptic with the photo didnt work!

this one date wise is obvious... (same car as well)
so... what is it off, do the numbers mean anything else
(other than Oct 1951)

Cheers

Indeed it is, the original coil for my '52 80".

any ideas people what the numbers can tell us (if anything?)

feel free to post your own bits etc and hopefully we can all learn along the way. (drag bits out of your spare buckets if you have to!)

Now I am no GP but does the 12v= 12v and 1051=10/51

Are you sure 10 means October? I thought LUCAS parts were dated by the week? In this case the 10th week of the year. Anybody? .W.

Thats interesting!

The radiator is dated 10/51, rims 10/51 , so assumed oct /51 as is a 52 80"

but nothing to say this was not made earlier than that... anyone else heard that theory?

i just had a look at lucas parts on google images and even though i could not find mnay dated ones they were all 12 or less.
You could be right though.
