1950 Caterpillar D2 Swamp Track for sale/trade

I have a 5U5858 D2 for sale/trade. Both engine run great. Has some slobber coming out of the exhaust from not using it enough. Tracks are in great shape. Pictures down below. If you are interested send me your email or number. Would be willing to trade for other crawlers. On the lookout for a good running BO Lindemann or a Caterpillar Ten. Located in Woodstock IL. Thanks! 

Why are one track on backwards.?
Bob

What am I missing, Bob? They look okay to me.
Pete

The left track chain is on ass backards and the pads are on the chain backwards.
Bob

Wow. Something I never would have noticed. I had to go check my 22s to see the chains on them. I've got a set of chains and pads that I might have put together wrong before this.
Thanks, Bob
Pete
