Dear Rob, thanks for your Help, my English is very simple , also understanding sometimes too difficult, but !!!
I Need two or, if not too expensive, four Windows to open from left to Right or opposit direction,
in Alu like Mill finished & clear glass like your Picture , which i can fix from the Outside .
I do not understand, what they mean by " Offside " or " Nearside " and the Size must be under 23 cm ( unfortunately I have only a clear height / Level between the upper and lower Frame of 23 cm )
in High and about two Peaces in 40 cm width & Maybe two Peaces in 60 cm width ( The height is Always max. 230 mm ),
i`m thankful, that you try to help me
