Winchester GQ4052 ? 38 special box

I came across this box which the current owner knows nothing about, and I cannot find any reference anywhere to it. Quantity of 18 per box is kind of different. Is this a known box or catalog number GQ4052:

3x6 = 18. Very generic and “un-American” in appearance (IMHO). Export? Three cylinder loads for a .38 Special, maybe for a country with restrictions on ammunition quantity posession?
