hallo john,
i looked a bit through my files. it appears that the tailskid was at least very simmilar on all aviatik types. they was very methodical. could be that the fin was adapted a bit on different types but the skid itself and the way it was attachd was the same.
see enclosed sketch. it is for the type 37 twoseater but was interchangable with 38.
cheers
