Hi Garth,
Many thanks for sharing those photos and detailed notes on the histories of these two cars. I hadn't seen that photo of SN MW 915 before - a very elusive car. I am left to wonder if this tool car ever left the north end. I know from your previous messages that the former-NE cars typically stayed on the north end, and I've never seen any indication (photographic or otherwise) that MW 915 ever strayed south of Sacramento. A shame, as that is a very interesting-looking car that would make a nice model.
I hope your recent health problems are now in the rear view mirror and that you're doing well.
Best wishes to all for a happy and healthy New Year,
James
