Thank you for showing these examples.
Very nice and well presented!
Thanks a lot Larry, now I can compare my (undated) 327 against the ones in your post to determine its age. I do have a question about the generators. On my 327 and my (both undated) wall (bracket?) and table lamp I found both the straight (77?) and piggy tail (99?) generators, not the R55 (with cleaning needle). Can you put any dates/years of usage on those? Thanks!
All the best,
A very nice and useful presentation, thanks for sharing.
Well documented information, thank you for sharing.
US lanterns : Q99 coil was standard equipped new on all 327 from the beginning 1916 to their ending, last known date stamped 6/7 July 1936 (image shown above).
The Q77 straight came about from the performance failure of the T88 straight (with internal pricker), both were standard new equipment on the introduced 220/228 slant in 1928. Q77 was also an advertised economical substitute for Q99 targeted to extended service users requiring frequent generator changes from carbon build up.
The R55 with internal pricker and a control mechanism showed up about late 1929 as an upgrade on instant lite 220/228
(some generator boxes state from a 1923 design) ?
R55 became advertised new standard equipment starting in about 1937 on US L427, while it had already been the standard new on Toronto 427K (kerosene) since 1935, kerosene required frequent tip cleaning while in operation.
Mica Globes :
QL dimensions began 5”X5” same as torch lite 323, with a wide integrated reflector and swinging match lite door, tabs were altered to the bottom of vent to secure mica when operating the door. After an official Coleman number change September 1918 QL became LQ , “Both” 323 torch lite and now LQ mica dimensions changed to
5 1/4” H X 5”, eliminating the need for tabs on vent, the LQ reflector was now taller and narrower, the change was gradual.
In late 1924 LQ mica changed again to a sliding up and down window.
