Franz Thiele 8x72R x 16 ga Cape Gun- Info about maker wanted

Hello all,

I acquired this Cape Gun June, 2017. It was made by Franz Thiele (Teplitz, Czech - Austria Hungary) This Thiele Cape Gun is a Rifle/Shotgun combination, being opposite to my other Cape Gun which is Shotgun/Rifle combination. The rifle barrel on this one has a set-trigger feature, and a single blade rear site that can be folded flat into the rib so as to not obstruct your view when shooting the shotgun barrel.

Specs are: 27" bbl - 6 lbs 9 oz - 13-7/8" LOP - Flip-up Rear Sight - Set Trigger (rifle)
Markings are: "F.Thiele in Teplitz" - "9515.01" (old marking) - "1648.g" "847.234.27" "Nicht Fur Kugel" (not for ball) - "16.0" "8.3"
Features are: overall engraving, case colored action, scalloped buffalo horn grip cap, buffalo horn butt plate, lever forend release, sling swivels

Although I've found a few guns made by Franz Thiele, I can't find any information about him or the time of his gun building.

I'm hoping that someone might be able to help with info about Franz Thiele.
