The Tschapka looks perfectly real, it has its obvious flaws of course but most can be addressed with minor repair.
Sorry Ron, I do not believe there is a missing stitch line from the top of the visor between the two split brads. The three Tschapkas in my pile (collection) all have hidden stitch lines with a rolled top edge, the stitching cannot be seen from the front as on other pickelhauben. Ron you may be correct on the field badge, without more detailed photos, or better, holding it in ones hand, it's tough to tell. R-Ungern you might place the feldzeichen under an ultra violet light to see if it fluoresces (glows).
The missing liner tongue and evidence of red-rot on the liner, well, it's nearly 100 years old and it is what it is. Good Score r-ungern :thumb up: Have fun bringing it back to life..
