I've always understood that the 1Q (a '1' inside a 'Q') stood for top-quality / first class quality and was an export-related thing... _________________

I think greg means the symbol on German lenses.
There are many symbols which can be found on German and CCCP lenses:
CCCP
Manufacturers logos :
http://cameras.alfredklomp.com/logos/
http://www.zenit.istra.ru/qa/qa-logos.html
- MC - Multi-Coated, multi-layered anti-reflexive coating (appears at 80' on CCCP optics)
- MS - appears on some export lenses e.g. Helios 77M. Just a translation mistake of "MC" (C in cyrilic means S in roman alphabet)
- Π - Russian letter P, analogy to Zeiss T, abbreviation of word "prosvetlenije", which means...something like "transilluminated" - simply: coated (on CCCP optics from the beginning of 60')
- P - see Π (letter P was used for export products)
- T - means optics designed for TV cameras usually
German optics
- 1Q - Q with number 1 inscribed means "Erste Qualität", first quality (1Q marked lens can be used for export)
- Δ - triangle on German optics means version for transport. There can be other symbols inscribed in the triangle:
- 1 - export quality, first class
- 2 - export quality, second class
- S - export quality, special (?)
- MC - sometimes in red, means Multi-Coated, multi-layered anti-reflexive coating
- T - better version of Zeiss coating called "Transparentz", which transmits 80% of light. Developed in 1935, but till 1940 used only for army purposes. Some T marked lenses can have better iris (more blades - e.g. some pre-set Biotars)
- T* - Zeiss, MC layers which can transmit at leas 90% of light. Used from the beginning of 70' by Zeiss Oberkochen
- V - Meyer Görlitz, means "vergütet" - coated. Meyers V coating on inner lens elements is extremely soft and can be damaged even by harder brush
