"HONGZ" stands for HO scale, N scale, G scale, and Z scale.

Post your non-O scale stuff here!

George D Stock of Philadelphia is the father of American HO (3.5mm) scale / gauge .
1929 Stock began building his Diminutive and Obstinate Railroad..HO gauge , outside 3rd rail.
Stock began promoting the gauge with articles and selling late 1934...and offered the first American HO engine kit at the end of 1935.
Stock was a very talented custom builder of engines in HO & O scale and is well known for his outstanding painting / striping & hand lettering.
Stock displayed his D&O layout at his hobby shop ..the outside 3rd rail was replaced with 2 rail around 1950.
To see Stock's first engine run please see link

Interesting how things come together over the years.  A year or two ago, in one of my old model railroad magazines, I saw a World War II era ad in which a manufacturer said they were turning over all their service work to George D. Stock.  I noticed the address, 83 W. Sedgwick Street, was close to Henry H. Houston School which I attended for 7th and 8th grades and had a classmate with the last name Stock.  It seems now that he could have been a relative (grandson?) of George D. Stock.  If only I had known then what I know now.

It is interesting to me that the first HO scale locomotive was developed in the neighborhood where I grew up, albeit over a couple of decades before I was born.

How is the locomotive marked to identify it as a Stock piece?  My 3 Stock GG1s are all stamped on the bottom in what appears to be done by hand and are postwar based on the sand cast brass shells.  My unbuilt kit is marked 1947.

I have always been interested in the Stock steam locomotives, but just never know what to look for.

Another great find as always.  Thanks for sharing.

I'm guessing he made his own motor for that - I don't think there were any commercially made motors small enough for a true HO scale model. When you flipped the engine over the wheel treads look like it had been run quite a bit - the need for some table thumping ala Flyer models came to mind. 

The snap with the Zephyr is intriguing - was that a one-off model, or was it available as a catlog item?
