WTS/WTT Pre 1937 Colt 1911A1 Mag

I would like to sell or trade this mag. I have been told it is a pre 1937 Colt 1911A1 mag. I'm asking $30 plus shipping or credit toward a trade for a WWII General Shaver 1911A1 mag, WWII MS Little 1911A1 mag or straight trade for a WWII Scovill 1911A1 mag, IS M1 Carbine mag or AI overline/underline M1 Carbine mag.

For payment I take PP/FF, Zelle or PMO

If a sale, the first I'll take it gets it, if it is a trade offer send me a PM with the offer please.

If you feel that you have reason to believe that this is not a pre 1937 Colt, please do not hesitate to let me know. I trust the person that told me it was but, I do not have the experience to identify it myself and honesty and transparency are important to me.
