Let's pool our resource here to identify the model years for these Brazilian Volkswagen Typ 1 series 'Fusca' for the IMCDb.

I'll start here: I found one from WikiCommons web site at File:VWB 1500 Fusca.jpg.

The 1.5 engine (as seen on the photo) was available between 1970 and 1975, and taillights match with the mid 1970s model, about 1974 or 1975.

I gonna make a research about the Fusca and post the details here

Here's the resume:
Volkswagen began make the Beetle here in 1957, the engine was the 1200
1960 - Turn signals in the fenders
1961 - New tail lights
1965 only- optional sunroof (extremely rare) and the Pé-de-Boi model ( http://4.bp.blogspot.com/---pX22bcwx0/TdpeXKhfqcI/AAAAAAAAAf4/vEWXphNKJmM/s1600/pdeboi18ed.jpg )
1967 - The 1200 engine was substituted by the 1300 and also came the 1500 engine. Also came new bumpers, new tail lights, vents in the engine hood
1973 - Vertical headlights
1974 - The 1500 engine was substituted by the 1600 and was introduced a sporty model, the 1600-S (the super Fuscão) http://3.bp.blogspot.com/_DNoNWWq35Is/TJzlnG66X0I/AAAAAAAAABo/Fthu06Jr47M/s1600/- p16.jpg )
1978 - External fuel tank nozzle
1979 - Fafá de Belém tail lights (or elephant foot)
1982 - Rubber protectors in the bumpers
1984 - Fusca became the oficial name
1986 - The Fusca stops being manufactured in Brazil
1993 - Presidente Itamar Franco asks Volkswagen to return the Beetle production, now with body colored bumpers and an adhesive stripe in place of chrome trim ( http://1.bp.blogspot.com/-x06Mg3MPrgc/T2CPvpREvGI/AAAAAAAAB_s/ohfqx9F9I34/s1600/s_MLB_v_F_f_228224231_334- 8.jpg )
1996 - The Fusca stops being manufactured in Brazil again

Thanks for your research, Crown Vic Guy Br

You're welcome, if you need anything about Brazilian cars, just ask

Three additions:
1970 - 5-lug wheels (with square air vents); modern bumpers without overriders.
1974 - banana vents behid rear side windows.

Didn't the larger oval taillight was introduced in 1962 model year?

I've found 61 models with both tail lights, must be a mid-year change
