220/228 B
Here is a hopeful attempt to help with component time frame identification. Please keep in mind nothing is definite concerning Coleman’s production as there was always some bleed over with all products, likely due to parts mingling of new design while dispersing older stock.
1 : Sunshine logo may or may not exist on side of fount 1930-33
both type are found with
*No Definitive Pattern.
2 : Long eccentric block transitioning to short in October 1930. Some may still be found in 1931 with bleed over.
3 : Key hole shaped frame where bail enters with fitted bail “swedged” upper side only (removable) ended mostly 1930.
4 : Key hole shaped frame where bail enters with “Round” bail end with cotter key retainer transition in 1931.
5 : Round frame hole with Round bail end with cotter key retainer 1932-41. 1941 on “swedged” 2 sides upper and lower (non removable) later.
6 : Some had brass direction disc on valve wheel some had aluminum. 1930-31 both type are found with
*No Absolute Pattern.
Aluminum mostly, brass occasionally 1932 - on.
7 : Winged smooth filler cap 1930-32. Three piece found mostly on later ones so bleed over is evident.
8 : Screen on fuel feed tube entry 1930-32.
9 : 220B stamp on bottom of fount on all 220/228B 1930-34,
with Instant Lite Stamp.

11 : 220B vents are brimless 1930- began transitioning in 1935. There is some early advertising showing brimless white underside vents with one example found on a government 220 B believed to be original.
Vents with brims mostly 1935- on.
12 : Frame rest(collar) lock seam fastened 1930-1938.
Spot weld fastened 1938- on.
13 : 220B lantern instructions included with new lanterns dated : 5/42 May 1942 :
Show ceramic burner caps and nut holder with part numbers, that never appeared in Coleman catalogs but show up on examples for a short time.
220BX lantern instructions dated : 10/43 October 1943 :
show standard burner caps.
There may have been a window of opportunity for these with ceramics.
