I was poking around my local jerry can emporium on my weekly visit....
When I found this water can / Sadly used for fuel by the red cap and red "P". Dated 1951. I would have never given is a second thought except that it has a M38CDN Canadian Army Number Stencilled on the side. An unusual non standard location for sure.
So whomever has M38CDN 52-30139 I have your original water/fuel can
and would be more than happy to reunite your jeep with it.
