St Peter's Old-Style Porter

I enjoyed this one recently and was wondering if any of the AHS extract kits would make a good clone. It doesn't have to taste exactly the same, but something fairly close would be good.

I don't know if you can get an extract kit, but here is the recipe that I will be doing this weekend. It is a small 3-4 gallon all grain recipe, so you'll need to fix it up if you do it yourself. I don't remember where I found the original recipe, but I know I did adjust it (in terms of size only) for the batch size I am doing.

6.00 lb Pale Malt (2 Row) US (2.0 SRM) Grain 85.1 %
0.35 lb Brown Malt (65.0 SRM) Grain 5.0 %
0.35 lb Caramel/Crystal Malt - 60L (60.0 SRM) Grain 5.0 %
0.35 lb Chocolate Malt (450.0 SRM) Grain 5.0 %
0.65 oz Northern Brewer [8.50%] (60 min) Hops 24.1 IBU
0.50 oz Cascade [5.50%] (1 min) Hops 0.5 IBU

Est Original Gravity: 1.054 SG
Est Final Gravity: 1.014 SG
Bitterness: 24.6 IBU

Mash at 154 degrees for 1 hour.

Hmmm...looks like it might be similar to the AHS London Porter. Thanks for the input.
