[CR] Help with 1950's? Legnano frame ID

There are 2 pix of the Legnano I mentioned in an earlier post here... http://www.flickr.com/photos/ciclismo_jewelry/sets/72157622553405575/

I am told it is a late 50's model but the seller does not know which. No tubing decals to help with the ID either.

Can anyone tell from the lugs and/or seatpost binder? Also, the traces of paint are what he says is the original color along with the red head tube (not burgundy as I had previously said...)

Thanks all
