Class C-41-190 drivers were evenly spaced, 5'0" apart, per D&RGW Folio #7.
BTW, Folio #7 has two sheets for this class, one for the engines with SH(sheet #49), one for those without(sheet #48)! Driver spacing is the same on both.
Also, there were two groups of engines classed as C-41 under the 1924 system on D&RGW, 1000-1030 (ex-1100-1131, Class C-41-190, Baldwin 1901, built as compounds) and 950-964 (C-41-185, Baldwin 1900, orig #901-915).
Not to mention Classes C-38, C-39, C-40(2 of these!) & C-42. All of these were ex-RGW engines except for the C-39 (ex Spring Creek Coal), all built (except the C-39, 1912) 1900-01, and all were gone by 1936-37 except one group of C-40's, #'s 930-934 (C-40-199, Baldwin 1901, Ex-D&RG 990-994, Ex-RGW 700-704, orig Vauc. Compound) which were all scrapped in 1945-46. Those C-40-199 engines were, btw, the last RGW engines (not built to D&RG specs like the C-48's of 1906) to exist as a complete class. All the RGW passenger engines were gone by the late 1920's and the only RGW engine to outlast these on D&RGW was #605 (C-26, Baldwin 1889, ex-#635, ex-RGW # 116) sold in 1951. Odd that, as the rest of her class was mostly scrapped in the mid-1920's with a couple lasting until 1934. #605 was at Montrose in the late 1940's up 'til she was sold, not much used. Real pity nobody saved her since she was the last "real" RGW engine.
Now you know why I so often list full-length class numbers (C-17-70, for ex.)!
