A 250 GTO and a 250 GTE (both RHD) shot in the 60s to identify.

Hello to you all.

As some among you who know me a little are aware, I also like Bonneville record cars and dragsters and I found something interesting on a fantastic website : http://www.oldstox.com/index.htm
More precisely, here : http://www.oldstox.com/EarlyBritishDragRacing.htm
There are some photos taken (in 1968 it seems) and two Ferraris can be seen : a 250GTE and a 250GTO.

Look for the GTE :

And here is the GTO there : http://www.oldstox.com/images/Drags%20from%20Brian%20Stewart%20euro/healey.jpg

I think it's #3729GT as this car is RHD, has three side slots and was white.

Could be pale green #3505GT but it has only two side slots in the fenders and #4491GT is much too darker a hue to be it (and also two slots...).

I think someone will be able to identify the GTE. Reg number is not entirely visible but I think it's YB or YP 30 or 38. (Y and might be V also ..)
Car is said to belong to J.A. Pearce ... (competition cars are usually linked to his name)
