Help identifying this Ferrari, possible 625 TRC Spider?

My father was doing some cleaning up and he came across some old photos of his, and one of them is of a 1950s (racing?) Ferrari. From looking around online it appears to be closest in appearance to a 1957 625 TRC Spider bodied by Scaglietti. He believes he took the photo in the mid 1970s right at or around Lime Rock Park in Connecticut. The only thing about this car that looks different from the 625 TRC Spider that I've been able to find online is the lack of a hood scoop.

If this attached photo is too small to be of help, here is a link to a huge version of it http://i.imgur.com/kFPqZLx.jpg

I'm sure someone here can figure this one out.

That looks like it could be it with some new paint getting rid of the black stripe it had. I didn't notice that little scoop on the top of the passenger side fender until I looked up that car but I can see it now. Thanks
