Craigslist Haul

TomKro: The item marked "E" I believe is a hand held RPM reader. It is used with a stopwatch and when set to "zero" before applying it to the end of a rotating shaft you can (feel/see) the dials rotating and when you hold it for whatever fraction of a minute you can then figure out how many revolutions the shaft rotates. The dials are read somewhat like you would read a watt meter and the reading multiplied by the time of measurement corrected to a full minute, giving you RPM.
 
I would never have guessed the use of the surface gage pins or the rev counter.

I looked on-line for pics of other "speed indicators" and saw one with a built in stopwatch. It's crazy what we take for granted with the electronics all around us.

Thanks a bunch for all the info.
 
That's a helluva deal. The serial number puts it somewhere in the 20's. Most likely 1922. There's 2 sources I use for dating. http://vintagemachinery.org/mfgIndex/detail.aspx?id=1617&tab=5 is a pretty good resource and you will find lots of additional information and pictures there. Also http://www.wswells.com/sn/sn_db.htm is a great database that is constantly being updated. I encourage you to submit details to both. Also you can get an original copy of the serial card from Grizzly, which I have for both my SB lathes, then you will have the actual, rather than best guess date.
Good Luck and enjoy your lathe.

Canus and craptain, thanks for the links for helping to date the hardware.

The first time I looked I failed to scroll down far enough, but I do believe 1922 is really close. That is pretty old for a functional machine. Just a few minutes ago, I managed to loosen the carriage rack screws so I can "de-goo" the bed. I don't plan on messing with the black finish, just getting it cleaner so I can bring it inside.

22 is definitely older than mine. I have a 1937 model 450, currently for sale. Mine holds far better tolerance than I am capable of achieving. Old is not necessarily worn out.
