Grill Type 3 Cent Washington

Does anyone know what grill type this is?

Thank you!

It's a doubled E grill with one set of impressions being a split grill.

sinclair2010 is correct. In addition to being 14 points wide, the partial horizontal row at the bottom of each grill is an E grll characteristic. Partial vertical rows, when they occur, are a characteristic of Z grills.

Sinclair2010 and cfrphoto: Thank you for taking a look! I do have some questions. I've included another picture with arrows. Are the partial horizontal (rectangle) rows at the top and bottom of the grill included in the vertical count? As you can tell from the number of arrows, I got 14 * 18. The horizontal is fairly easy to distinguish as 14, but the vertical is less clear. Did I add an extra arrow? If so, where?

Thanks again!

I do see the two partial horizontal rows he's talking about and I'd be curious to know if those are typically counted or ignored when determining grills. Thanks!

This actually looks like a triple-grill to me - one partial at the very top of the stamp, and two connected grills at the middle/bottom. Can't say I've ever seen this before?? Am I seeing things??

The partial grill impression at the very top and the one at the bottom without the second grill impression in the center of the stamp would be called a split grill. Because of the second grill impression the stamp can be labeled a double grill. Putting the pieces together makes the stamp a double grill with one of the impressions a split grill.

It would be reasonable to count one partial row as a row, but if a partial row exists top and bottom, the two partials would count as one row. Partial rows occurred because a screw machine was used to scribe the horizontal grooves around the circumference of the grilling cylinder while the vertical groves were scribed parallel to the axis of the cylinder. Multiples exist confirming that partial rows differ from stamp to stamp.
