Ken and Mike, thanks for the info on the Ideals. It looks like mine is the one in the middle picture, or most common No. 5. A couple of questions.

Is the operating handle on the No. 5 in the middle picture in the proper position, or should it be closer to flush with the measure body ?

It looks like mine is missing the drop tube [brass ?]. Any place beside ebay to pick one up ?

Thanks, Daryl
