Recently got lucky and scored a Lambert brass PRR H6sb 2-8-0 on an on-line action. Is beootifylll... However, I have usually tried to stick to my Chosen Era - 1952 - to guide my modeling, and I have learned that the H6sb may have been retired before 1952. No, I didn't do my homework before bidding.
SO, can anyone enlighten me as to when the H6sb was officially stricken-off-charge from the PRR? I know they lasted into the '40s; any into the '50s?
Thanks for any help
