This is an NLR no.38 Due to lack of photos and information this sprite is somewhat inaccurate. NLR no. 38 was built by Beyer, Peacock & Co. in 1860 as an 0-4-2st (idk if it is a saddle tank or not). NLR no. 38 would be used for short distance trains and shunting. It would get an overhaul turning it to an 0-4-4st.
