Unusual Israeli .50 H/S

I recently got a .50 Cal. with an Israeli h/s style I’ve not seen before. Is there any special significance to it? I’ll try to post a pic later.

LOT 1 TZ 82 12.7x99 M 8

Jon, we bought from the israelis .50s and I have that same headstamp in an AP round with black and also one with red primer annulus. And tracer marked M20.

Looking forward to seeing a picture when you can Jon. I love Israeli stuff!!!
