Description

Army Unit Crest
Please see the picture. This is an hard to find DUI/Crest for the unit shown.  It is in the condition shown. May have some wear from having existed over the last 50-70 years.  Out of a collection. If there is ink writing on the reverse, it comes off easily with a little alcohol.
Unit= US ARMY 1st MACHINEGUN SQUADRON-hard to find unit
Fastener= screwback
Maker= no mark
Time Period= ww2 era (likely pre-ww2)
Condition=as shown in pictures, in original condition from a small collection of nice early ww2 crests
Please ask any questions before bidding and as early as possible. I don't do refunds as the items are clearly pictured.
I charge .75 in the USA for this shipping which is what the materials and shipping actually cost me. I will combine shipping on multiple items and I can ship several crests for the same price.
International shipping is either 18 usd (airmail) and this covers my cost. (the US Postal Service has this crazy price, not me. Thanks).
