You have another possibility of loading pictures in a web base photo storage, like Yahoo Photos and then give us the link so we can see your pictures. Now, about the pictures, take pictures of the all bicycle and also of details like stem, handlebar, hubs, bottom bracket, cog, chain ring, cranks, seatpost, etc, etc. And please if the bicycle is "70 years old" let it alone for a couple of hours more, until we see the pictures and may identify what you have.
