Does P2K Southern Pacific ALCO S1 switcher represent its prototype?

Does anyone know if the Life Like Proto 2000 Southern Pacific S1 switcher, road number 1019, represent it’s prototype correctly?I saw a photo of an Southern Pacific S1 switcher (from http://espee.railfan.net/nonindex/s01_photos/1018_sp-s1-don_jewell.jpg), that had a road number of 1018, but it had 2 large grab iron wires on the top of the front hood along with 2 blank nunber boards and this loco had no bell and had a higher exhaust stack.These details are not on the Life Like Proto 2000 Southern Pacific S1 switcher, road number 1019, so does the Life Like Proto 2000 Southern Pacific S1 switcher, road number 1019, need these extra detail or did its actual prototype not have these details?

If you look at the switcher behind 1018 it does not have looped grab irons or the large number boards. You have to ask yourself is it protypical as delivered or after the shops modified it. I do not think 1018 had these modifications when it left the factory. With a little work and a change of one number you would have an orginal protypical model of 1018. Enjoy and I hope this helps.
