Serial Number 270260 was reported as inaccurate.

Note: regulator is 'not' micrometer. go see movement
picture: item # 282551001101
Curator Response: Thanks for the report. It appears the adjustment mechanism on the index is missing. See the "Rockford Unknown" regulator for comparison. The standard plain regulators do not feature the bar spanning the index plate but the micrometric examples do.
