Rare D&RGW items for sale on Ebay

As a shameless plug here, I am listing a few extra items that I acquired in the 1970's from the estate of Jack Berry, who was D&RGW trainmaster in Alamosa until he retired in the early 1960's. The items include a 1938 D&RGW Operating Rules Book--this was the edition that governed operations on the narrow gauge in later years. Also a 1946 D&RGW rule book on air brake usage, etc. There is great stuff in both books. Finally, two sets of switch keys and locks. The first is a set of D&RGW Adlake switch locks with a D&RGW key. Mr. Berry labeled them as having come "off the narrow gauge", but I don't know where. The second set is a rare brass heart-shaped D&RG Adams and Westlake lock and D&RG key. These items were labeled by Mr. Berry as having come off the "Gunnison Lines". I am starting with low bids on these items, so it might be a chance to pick them up cheaply. I would like to see these items go to NGDF members as I know they will be appreciated. Here is the link to the items:
