Serial Number 6308513 was reported as inaccurate.

Note: Some are open face and some are hunting. Look at
the placement of the mainspring winders with the
positining of the stem. Your pictures show both
open face and hunting but you changed the
classification from hunting to open face when
these were in fact mixed runs.
Curator Response: Thanks for the report. The images displayed are from various runs, not isolated to this particular run. Waltham serial ledgers explicitly designate this run as hunting configuration, supported by the images of #6308513.

Serial Number 6308367 was reported as inaccurate.

Note: NOT a hunting case. Mine is an open face....all
original!
Curator Response: Thanks for the report. After reviewing images of the watch, I determined the serial number is actually "6309367" which correctly corresponds to an openface No. 20 movement. [eBay #312183605365]
