Tim,
The brass plate on the change gear cover is most likely something added by the local owner. Certainly not something that Atlas put on it.
On the serial number, the "V" is OK. We've had reported a few with either "V" or "H" in that position. They apparently stand for either Vertical or Horizontal, and refer to the countershaft assembly type. One of your photos shows a vertical countershaft, so that is all right. But the serial number has too many digits. The highest known 10" serial number is under 90000. The year that the 10" production ceased, the 12" Commercial begain production at Serial Number 100000. Most likely, the final character, which you show as the numeral "8" is actually the letter "S". There are many reported examples of this up to serial # 20318. All such are babbit bearing models, so one theory is that it stood for "Standard". The only Timken model that we have in that range does not have the "S".
So please recheck the serial number.
