220 identification

My haul today, but I have a question about the 220. I thought it was a 220B but the bottom shows a 220P. Any ideas?

 

Is there a date?

That is a light strike on the “B” making it appear as a “P”.
Even the “228 B” was stamped “220 B” in the 1930-34 era.

 

Tony I do not see a date on it, should it be under the Coleman sunburst?

I was thinking a light strike also.

 

Fine fettling projects!

 

A light strike would make sense - but it does not really look like one. I do not believe there ever was a "P" - "proptotype" ? pure supposition.

 

I wonder if there is anyway to verify if it is a prototype?

 

I will defer to @coleman54, a recognised expert I this field of Coleman variation identification, but… what would it be a “prototype” of and why?

Mistamping, wrong stamp, or a damaged stamp would seem the most plausible explanation.

Cheers

Tony, thank you. As a newbe at this it just sparked thinking it was a Yunicorn.

 

Thanks @Tony Press

In order to see if there is anything visually unique with your lantern components we need to see some clear complete images of them for instance :
The complete burner
Mixing chamber (both sides)
bale attachments
font bottom baseplate (complete)
fuel filler cap and bung
Pump
Valve

 

Here's a handy guide for the B model

Thanks Toby,

Now knowing where the date is, it's a Jan. 1933.

 

Is there anything like that available for the 236 as well?

 

Toby are any other on PDF like the 327 and 427?

 

@Martin K. Unfortunately, not that I'm aware of. Mike Sine has a fantastic US 237 document, but it would not translate well to most 236's as so few were produced here in the US.

@Sac not at this time, however it is in the works. Be patient please as there is a lot of info and pictures that need compiled. In the meantime you're welcome to PM me with any questions and I'll help with the best of my abilities.

 

Thanks Toby. I will be patient.

 

Then it would be even more interesting to find something out about this one... From the Coleman book I found out that it must be from between 1941 - 1957. The mixing chamber is marked 5231, but no date codes anywhere.
