What model of Coleman lantern?

Hi guys
I have just taken possession of this double mantle Coleman lantern. Can anyone help with identifying its exact model and year of production and what fuel??

I have included a pic of the lantern and also a pic of what's on the bottom of the fount.

Thanks in advance
Simon

 

Its a white gas model....dont want to call it a 220 but it sure as hell looks like one.

It's a 220 and the link below shows the relevant gallery images.

L220, 220, 228, B to K Variants

 

@Simon Henderson

If I’m right in reading the stamping on the base of the tank, it’s a “2” on the left of the Coleman logo and a “7” on the right. So… that would indicate July 1942 if it follows the stamping pattern shown by @Toby Garner here:

7/1942 Coleman 220B


I see also what looks like “US” stamped above the Coleman logo. Toby’s lantern does, too. Are there any other letters associated with the US stamping?

Cheers

Tony
