ALCO RS-3 NH paint scheme question

Hi I am new to the New Haven railroad and i would like to have some help on the issue of the paint scheme
I am reserching the ALCO RS-3 road switchers of the NYNHH as made by ATLAS HO
This locos have n.537 and 560 they have an orange/black paint scheme with a black logo on the cab sides.I know they were relised in this paint scheme in 1953
Can anyone tell me how long did this locos last in this paint scheme and in the format modeled by Atlas ?
thanks very much for your reply

You may want to visit the New Haven Technical & modeler's society. They are more tuned to this type of query. http://thenhrhtanewhavenrailroadforum.y ... sions.html

A black logo on the cab side? There's no known NH RS-3 scheme that had a black logo on the cab side. I looked through the Atlas online catalog and can't find any New Haven HO RS-3 in any scheme, so for the moment i am somewhat stymied. I can help you with just about anything you want to know about NH RS-3 schemes -- what's right and what's wrong. Can you post a picture --- or a pointer to a picture --- of the color scheme you saw?
