<p>[QUOTE=&quot;springfld.arsenal, post: 111173, member: 54&quot;]About 6 x 12 inches, about two lbs, I&#039;m sure it came in some wonderful case but I didn&#039;t get that.&nbsp; Got it from a PA militaria dealer at a show about 20 years ago and never investigated it till now.&nbsp; Has many moving parts, it moves in every way you can imagine.&nbsp; Made by Buchi in Bern (yes U should have umlaut, too lazy to look up that code today.)&nbsp; Should be ca. 1930 by way mfg stamped company name, they were around from 1871 till recently, a family company which made a lot of items for Swiss military.&nbsp; I already posted on a specialist forum, British Ordnance Collector&#039;s Network, asking ID.&nbsp; Since the important &quot;operator&quot; marks are in English, perhaps made for UK or US military?&nbsp; I know this is a computer for indirect artillery firing, but don&#039;t know the exact purpose.&nbsp; The circly thing probably held a magnifying lens at one time, that must be where you read the result of the equation this device solves.&nbsp; ???</p><p><br /></p><p><img src="https://springfieldarsenal.files.wordpress.com/2016/01/img_1624.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> </p><p><br /></p><p><img src="https://springfieldarsenal.files.wordpress.com/2016/01/img_1613.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> </p><p><br /></p><p>Less important photos:</p><p><br /></p><p><a href="https://springfieldarsenal.files.wordpress.com/2016/01/img_1612.jpg" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://springfieldarsenal.files.wordpress.com/2016/01/img_1612.jpg" rel="nofollow">https://springfieldarsenal.files.wordpress.com/2016/01/img_1612.jpg</a></p><p><a href="https://springfieldarsenal.files.wordpress.com/2016/01/img_1611.jpg" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://springfieldarsenal.files.wordpress.com/2016/01/img_1611.jpg" rel="nofollow">https://springfieldarsenal.files.wordpress.com/2016/01/img_1611.jpg</a></p><p><a href="https://springfieldarsenal.files.wordpress.com/2016/01/img_1615.jpg" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://springfieldarsenal.files.wordpress.com/2016/01/img_1615.jpg" rel="nofollow">https://springfieldarsenal.files.wordpress.com/2016/01/img_1615.jpg</a></p><p><a href="https://springfieldarsenal.files.wordpress.com/2016/01/img_1616.jpg" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://springfieldarsenal.files.wordpress.com/2016/01/img_1616.jpg" rel="nofollow">https://springfieldarsenal.files.wordpress.com/2016/01/img_1616.jpg</a></p><p><a href="https://springfieldarsenal.files.wordpress.com/2016/01/img_1617.jpg" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://springfieldarsenal.files.wordpress.com/2016/01/img_1617.jpg" rel="nofollow">https://springfieldarsenal.files.wordpress.com/2016/01/img_1617.jpg</a></p><p><a href="https://springfieldarsenal.files.wordpress.com/2016/01/img_1618.jpg" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://springfieldarsenal.files.wordpress.com/2016/01/img_1618.jpg" rel="nofollow">https://springfieldarsenal.files.wordpress.com/2016/01/img_1618.jpg</a></p><p><a href="https://springfieldarsenal.files.wordpress.com/2016/01/img_1619.jpg" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://springfieldarsenal.files.wordpress.com/2016/01/img_1619.jpg" rel="nofollow">https://springfieldarsenal.files.wordpress.com/2016/01/img_1619.jpg</a></p><p><a href="https://springfieldarsenal.files.wordpress.com/2016/01/img_1627.jpg" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://springfieldarsenal.files.wordpress.com/2016/01/img_1627.jpg" rel="nofollow">https://springfieldarsenal.files.wordpress.com/2016/01/img_1627.jpg</a>[/QUOTE]</p><p><br /></p>
