"On April 7, 1964 Harry Young, City Manager, Dallas Tailor & Laundry Supply, 502 Second, Dallas, Texas, advised SA R Neil Quigley and SA Thomas T. Trettis, Jr, he has been in the laundry business for over twenty years. Upon viewing the a photo of the grey cotton jacket, K42, he stated, in his opinion, the laundry mark in the collar would "030" and not "30 030." He feels the first "30" at best is a partial printing which did not take and the last "030" is the actual number.
He feels the "030" was printed by a National Laundry Marking Machine, in view of the spacing, which is wider than the normal marking machine. The National machine is spaced slightly larger, since it uses an inked pad rather than a ribbon in other machines. The extra spacing on the the National machine is necessary to keep the print from blotting when applied to clothing.
He stated the dry cleaning tag "B9738" was by Tag-O-Lectric Machine."
I believe the Tag-O-Lectric machines were made in Kansas City Missouri. Some where used in the Dallas area but the manufacturing was done in another state.
