	Thank you for sharing, New2brass , especially the picture of the two models, as well as the M8 Grenade Launcher. As far as I understand this, HF manufactured these as well(?) The M8 was long removed from service so for what purpose? You refer to "HF CO CCNLs 88,92,96, 127" at the bottom of your reply. Can you tell me where I can find that reference and read more about the HF Curved Barrel? Thank you! Anders

	Mr Hinden, the H in HF, was taking orders for the around the corner device. in the mid 70s. The attachment to the barrel was similar to the The Dutch blank firing devices, made by NWM of Holland The HF Co blank fire attachments started showing up in the mid 80s. They were much heavier but had a similar lock mechanism to the NWM devices. this is a picture from June 1987 CCNL 127 showing two 45 degree and one 90 degree as well as their copy of the M8 grenade launcher. If anyone has on of the M8 launchers please post pics of the markings The German Krummlauf device was clamped to the barrel. It also had gas bleed holes and a sighting system. We had reports of the HF Co around the corner device weighing in at almost 2 pounds! The HF Co device you have no sighting method and may be looking for your front sight when it blows off. I suspect the orders for these reflect why we do not see them in quantity. The US did experiment with a curved device for the M3a1 Greasegun post war and Korea There is a Forgotten Weapons video on the Krummlauf, I believe Ian says that the bullets would fragment, so it would spray pieces. The Myth Busters did an episode where they bent barrels. I wish they did a test showing the effects after 10 or 20 feet for more info: HF CO CCNLs 88,92,96, 127 NWM blank fire device CCNL 14 Edited by New2brass - Jan 16 2022 at 9:12am

	Thanks for coming back to me, Wayne. As mentioned it was manufactured by Hinden-Fleishman Co. in the 1960's - but who was the contractor and what was the purpose? I am dying to retrieve some additional information. I have not been able to find any info on the company itself. I doubt it is still in business...(?) Best, Anders

	Hinden-Fleishman Curved Barrel Extension for the M1 Carbine This is an interesting device manufactured by the Hinden-Fleishman Co. of Bala Cynwood, PA, which manufactured M1icon Carbine blank-firing adapters that used an identical spring catch and mounting collar. (Ref. "War Baby! Comes Home The U.S. Caliber .30 Carbine" Vol. II by Larry L. Ruth (1993)). Less than 100 of these strange accessories were manufactured during the 1960's. I hope someone in our Forum has additional information on this device, such as where the Curved Barrel was in service. History. The existence of any TM or User Guide. Carrying Case. Ammunition used: Standard or reduced load and so forth. Any information will be most welcome. Thank you.
