I've been riding around on a Brooks B-67 for 3 years now and it's been great.
I have been sitting pretty far back, almost on the rivets.
Wouldn't mind buying a different seat post that has a large off-set (or set-back, whatever the proper term may be.)
So far all I come up with is this.

At over $200 there is no way my cheap self is going to buy it.
My frame is a Trek 7200 multi-track (about 15 years old) and looks like crap so an expensive, lugged seat post is out of the question.

My bike gear knowledge is not the best but this forum has really helped. I don't know my seat post angle or anything like that. All I know is I want something with more backward adjustment.

I don't have the ability to take a picture of what I got but it is the original seat post.

Thanks for any comments you might share!

pretty good if you can use a 27.2

VO Grand Cru Seatpost, Long Setback

Here is one with 32mm setback for $33 (marked down from $149). Not sure of diameter.

FSA K-Force Lite Seatpost (100002146) at CambriaBike.com

Me too!

Only 1" of setback, but that may be all you need.

PS. Check the fore and aft position of your saddle. It may be too far forward. With the crank arm at 3:00 o'clock position, drop a plumb line from the prominent bone just under your knee cap to the foot on the pedal. The point just below the knee should be directly over the spindle of the pedal.

excellent suggestions! thanks.
not sure why all of my searches didn't come up with those ideas (using google).
I have already got the rails as far back as they will go.
You guys have saved me some money.
