Depending how flexible you are on the model, Cimarron does currently have a pair of 7 1/2" charcoal blue OT's with Army grips in .38.
Also, if you like 5 1/2" barrels, you might consider the '51 Richards-Mason, Cimarron has a bunch of those. I personally like the R-M more than the OT's, love that octagonal barrel and longer sight radius!
But there are lots of OT's out there so they show up used fairly often. Good luck!
