Seeking to Trade for 1957 Upgrades

[JTysver]

I'm needing a few upgrades for 1957. I wish to trade for them. I prefer ExMt and prefer to trade for ExMt, although I would trade for Ex condition on these. I willl trade the mid series cards for mid series cards only.
I have about half of the set in Ex or better condition to trade. I'd like to trade card for card. (Note- none are for sale)

Here is what I need...
004, 005, 006, 012, 039, 050, 067, 070, 086, 088, 091, 116, 118, 131, 132, 154, 164, 176, 214, 260, 326- mid series, 366, 393, 407

Here is what is available with shape next to them. Most of the ExMt and Ex are centered well, but I will post scans or notify you if there are any qualifiers.

I've got #s 12 and 70. Not sure if they meet your condition requirements, but I've included scans. Let me know. Thanks.
