I have recently aquired a 1919a4 browning and M2 tripod but after looking at various pics of tripods i am in need of some help, on my tripod is an angular piece of metal that is bolted to the flat plate, i have not come across this on any other tripod pics that i have seen. Is this a later addition? as i was hoping my m2 tripod was ww2 era, also on the tripod is a webbing strap which is attatched to the front leg with a leather tab, the end of the strap has a metal end which is far too new to be of ww2 vintage and i am very dubious of this. Can anyone help or offer any advice
