So I started taking the 397.19391 1/3HP flat top apart.
Cleaned up the light. It's nice to have a block grinder to clean up a block grinder.

Then I needed one wheel guard to put on my 397.19340 1/2 HP flat top.
Notice how's the round bump out for the arbor shaft starts squared off and has a smooth finish on the guard from the 1/3 HP flat top. My 397.19590 round top 1/3 HP guards are the same.

Now look at the guard on my 1/2HP flat top. It has a rough finish and the bump out for the arbor shaft is not squared off.

Anyone know if this is difference in year of manufacture, or is it a difference between the 1/2HP vs the smaller 1/3HP?
Anyone have the style on my 1/2HP and want to part ways or trade for the 1/3HP style that I have?

I had to pass on a nice 1/2hp flat top at an estate sale this morning (Reading). It was only missing the rubber feet and the quench tray (no stand). After a little digging I found them and reunited the parts with the grinder for the next guy.
