Harold: Ya thats the project im thinking keg on. its a narrow steel frame. No point in messing with the top tube / tank, might hold a quart ( mabey ) when done. I think I have my solution but will know more when I have spare cash for more parts. Pickle: The function of the cross brace is to look cool... Errr, I dont know.
Mabey sombody more knowledgable than I will know WHY they did this back in the 20's to 40's or so. ( but it does look dang cool ) and totally retro / vintage. Mabey Axel can help me with a German dealer for a Lepper seat. I'll have to PM him. OH! SO MANY SPRINGS!
