Some sellers on EBay would probably label it as ASF Ski Troops.  

I agree that it’s a stylistic variation.  No super secret ASF unit patch.  Thanks for your help,  Bruce Linz

I've heard in conversations they're older than other variations, but I have no real evidence to back up that claim. I agree with it being a stylistic variation.

. Hi mikie,   Yes I guess it was pretty in-tents when the guy couldn't pin-point where he's lost it   Norman D. Landing, Forum Normandy Correspondent, May 21  2O25.    ….        

Picked up this odd badge over the weekend I am not sure if its military or fire department related or the combination of both. 

I figured I'd show AustinO's referenced patched uniform here together with my variation of the 4th AAMGB Shoulder Insignia.  One would ponder as to why this particular organization (as small as it was) would even have a Liberty Loan insignia produced.  As it turns out E.H. Kluge Weaving Company was located down New York City and evidently a portion of the 4th AAMGB  troops had ties with New York according to the organizational reference above. To bring this kind of full circle, there was another battalion with stronger connections to New York, that also had their unauthorized but worn Shoulder Insignia made  by E.H. Kluge and that was  212th Coast Artillery N.Y.N.G. cicra. 1920’s. The First Army patch with red colored panel between the legs was representative organizations Shoulder Insignia. 

Thanks!
