If the only change being made to the drawing is a change to the company name and all other information remains the same (including the company CAGE code) then it sounds like they will simply fall under the provisions for drawings redrawn without chage as defined in ASME Y14.35M-1997, "Revision of Engineering Drawings and Associated Documents" defined as follows:
4.3 Redrawn Drawings
Depending on the circumstances, drawings may be redrawn either with or without change and shall include the original date and contract number as applicable.
4.3.2 Redrawn Drawing Without Change.
When a drawing, or a sheet of a drawing, is to be replaced because of loss, destruction, or degradation due to age, it may be redrawn without change. The replacement shall duplicate the requirements of the old original which is being replaced. The names of the individuals whose signatures appear in the Title block of the old original
and revision record, if retained, are entered on the new
original. The notation REDRAWN WITHOUT CHANGE with the signature of those who prepared the replacement and date shall be entered in the Revision History block. The advancement of the revision letter is not required.
Hope this helps out.
