<p>[QUOTE=&quot;all_fakes, post: 114515, member: 55&quot;]I&#039;ve had this mystery item for about 30 years, got it at a thrift shop I think, because I liked the quality....but have never been able to figure it out.</p><p>It is machined from nickel-plated brass, and the barrel is about 4 1/2&quot; long, 1&quot; diameter; with the plungers extended it is 17&quot; long, 13&quot; with the plungers in the shortest position.</p><p>The inner longer plunger with the T-handle ends in a disc with four round holes; the outer shorter plunger with the two-hole handle ends in a thicker solid disc.&nbsp; The plungers move independently inside one another, and fit the barrel quite tightly. When the ends are removed from the barrel, both plungers extend well beyond the barrel.</p><p>&nbsp; &nbsp;&nbsp; The markings are the letters D, B and T superimposed inside a circle; the words Standard Barrel and Made in Switzerland; and a cross with the number 124863.</p><p>Thoughts were:&nbsp; agitate a liquid sample with the longer handle while applying pressure to it with the shorter handle; or unknown medical or chemistry use.</p><p><br /></p><p>^[ATTACH]28761[/ATTACH] [ATTACH]28762[/ATTACH] [ATTACH]28763[/ATTACH] [ATTACH]28764[/ATTACH] [ATTACH]28765[/ATTACH]</p><p>[ATTACH]28766[/ATTACH]</p><p>[ATTACH]28767[/ATTACH][/QUOTE]</p><p><br /></p>
