Filling adapter for 200 bar compressed air

Nice quality item as you would expect from Walther, perfect fit in breathing air cylinder valve unit and also that of my pistol.
Both Helen and Andrew at EMRR are very helpful with any query you may have and will respond to questions asked about items you may be seeking to purchase. That for myself also included checking with me the item I was purchasing was the correct one that met my needs..thanks for that, much appreciated.
