I'm primarily a historical architectural model builder . I'm looking for any history anyone here might be able to share to me on a structure known as the Zep Diner . This much I know . It was built to commemorate the USS Los Angles Airship . I was razed about 1946 or so I am guessing . The known address was 515 West Flower , west of today's I-5 freeway . There is a McDonald's on the property now . I have constructed a 1-24th scale model using the few photos I have been able to find of the building .
