Greetings!
Please, help me determine the frame of a bike newly got for restoration.
I have found simillar frame components on a few Italian bikes but not the exact match.

The top of a seat tube is shrunked and distorted so the exact diametr looks like a question/ (seems to be 25.4 - 26.5 mm)

Fork seems to be non-native due to an odd \alien\ spacer in a headset.

No ID's or serials or stickers found. The red color seems to be original.












Thank you!
