Yep, it's a Del Fatti; ISP-LP, 15 Degree cant, Horse body with shark loops.
3 months is very quick for any kind of custom holster. Apparently, Del Fatti is trying to finish his huge backlog and then reopening the ordering in a limited fashion in order to maintain a 6-month wait. I highly doubt they can get it down to that wait time though.
Here's a pic of the backside with the Del Fatti logo:
