I noticed that as well , emilypate .
Yours looks more like 'bottle' pattern than honeycomb .
The uniqueness that it has suggests that your glass was perhaps made in your area , and with some down & dirty searching (such as who constructed the church , who their suppliers were & such etc.) chances are fair for you finding the manufacturer , IMO .
The fact that the pane you've depicted in your images has been cut by a glazier/craftsperson relates to the factual probability that the glass used was purchased in sheet form & cut-to-size @ the site .
I am assuming that this glass was not installed in a window that would 'open' .... relights , large ones such as the one you've described , were popular items way back when , esp in large rooms/churches/assembly areas , ... 'Bringing the Light' into people's lives was expensive , so day-time services were pretty common .
If you've got all 24 panes & they are intact , their value would increase somewhat , but I don't think you could retire on the sale of the set ...
Plenty of design/repurposing applications for your old mat'ls , though !
