FP,
A quick comparisson of a SS/VT Frog and a Waffen SS Frog is the following.
SS/TV Frog has:
1. SS Property Mark
2. SS/TV Standarte mark
3. Usually a date
4. Over 90% of the TV frogs have hilt straps.
5. The serial number of the bayonet will sometimes be found on the frog.
The SS/VT and Waffen SS only have a SS Property Stamp and sometimes a date.
