Odd Tender

[NW Modeling List]

I was looking through some of my N&W books yesterday for photos of M-2's and I found a photo of Z-1a #1460 equipped with a very unusual tender. It said it was made by combining 2 USRA tenders to increase the distance between water stops. Rather long, low and sleek looking, if not strange! The photo is very dark and details are hard to make out but it seems to have the Pilcher style 6 wheel trucks under it.
Does anyone have any further information as to when it was built and how long it ran? I gather it was a one of a kind creation.
Thanks for any information.
