Tilley R55 date code?

Where do I find the manufacturing date code on the R55 heater?

 

On the base plate of the tank, but some of the early ones are not date coded, Tilley only started date coding in the Autumn (or there about) of 1956.

 

So similar to Coleman dates on US produced lanterns?

 

@Blueflame

The date code will look like this. The last two numbers are year, the first one or two numbers are month. This is February 1964. Ignore the letters.



Cheers
