Help identify age of Carhartt Master Cloth overalls

[u-505]

Hello. 
I’m looking for help in nailing down a date for a vintage pair of Master Cloth Carhartt bibs. I’m not sure how to post pics of the item. Any help would be greatly appreciated.

Hi, I believe the mastercloth tag was near the tail end of the script logo era that lasted from 1910 till the mid 60's. I'm not overly familiar  with this time period for bibs but try the carhartt subreddit on reddit. They probably can give more info and have an age guide. They love stuff like this. I would link it but I'm not sure its allowed.
