The piano was built in 1924 when Chickering was part of the American Piano Company. Would have to do more research but it likely is 127. Scale 121 was the scale on the Chickering Quarter Grand which was a very small grand. Chickering had many models and scales because they where constantly trying to perfect their pianos. Few people realize they had their own in house lab, machine shop and that Jonas Chickering worked closely with Washburn to develop and make stronger piano strings. You may be able to find more information on scales on the Chickering Foundation web site at
www.ChickeringFoundation.com Bill Schull also is a good resource.
If you are trying to restring this piano you may want to use PScale and you may have to make a string pattern
