These are probably early teens, no markings. Chimney doesn't appear to be brass nor does the rim.
Here is a side view.
Here is the back. Thanks in advance!!
With a vertically opening door, these are probably truck. Some trucks came with gas lamps into the 1920's and were all steel. The general style did not change much as the lamp manufacturers continued to use the old dies, trucks usually were not a fashion statement.
Those are very similar to these on my 1923 YPC Bus. White Motor Co supplied me with many photos of their trucks fitted with similar lamps up to 1929. Steel bodies and brass or steel doors and tops. The rough roads tended to age crack the brass. Many times the brass trim was painted on commercial vehicles. There were several makers and variations. Mine do have the 4 carriage bolts in front and back. Many of these vehicles used a magneto for ignition and no battery so electric lights were not an option.
Richard, those do look close to the ones I found. I am going to look at the tops and rim closer to see if it is brass that has been painted. thanks for your input. Are you coming down to the Payette Swap meet, Sept 12 (I think).?
Marvin, I think they are the same the more I look at them. I couldn't find a name on mine. I probably won't make Payette. Boise was fun.
