Are you sure the "valuation" map was 1907 and not 1917? The valuation project did not begin until the law in 1913. It still could be a D&RG map of 1907 but not a "valuation" map.
The Colorado Railroad Museum has just recently completed making half size reproductions of all the US Valuation Maps of D&RG for sale in three sets:
1. Alamosa to Chama
2. Chama to NM/CO State line near Navajo inc RGSW
3. NM/CO State line to Durango
Please call them for prices which are reasonable.
