A request for some information

To whom it may concern, I hope this message finds you well. I’ve been following the historical photos shared on the Chicago Area Fire site, and I’ve found them both fascinating and inspiring. While researching my family history, I came across some old photographs that I believe might be of interest. A friend recently suggested I share them here to see if any experts could help identify the dates or provide more context. I’m currently trying to determine the time period and other details for these three photos (attached). Based on what I know about my great-grandfather’s service, I think they could date back to between 1918 and 1924. This is partly because his fireman’s badge has "1918" engraved on it, and he was involved in the Curran Hall Fire in 1924. It's possible the men in the photos are from Engine Company 5. However, I’m not very familiar with the uniforms, equipment, or specific details from that era, so I’d really appreciate any insights from those who have knowledge in this area. If anyone can help identify the location, time period, or even the names of the individuals in the photos, I would be incredibly grateful. Thank you in advance for your time and assistance. Best regards, Anne
