Does anyone know what alloy the original stamped ribs were fabbed from in 1946 ? Need info for IA. Thanks.

Re: 46 stamped ribs

I have not found any clear markings on them but after reworking all my 46 BC12D ribs, I believe they were 24st ie 2024 T3 and 025"
I used 2014 T3 to make several replacement nose ribs, aileron bay false-spar, plus many doublers and patches.

Wing parts and top cowlings seem to be the only areas where 24st was used.
