P17 Bayonet without grooved grips.

I can confirm that the Brit P13 bts and the US M17 bts are 100% interchangeable on the P14 And M17 rifles.

I once had an individual tell me his bayonet didn't fit his rifle. I forget what rifle it was, not one of these. The bayonet lug or mortise slot was hammered, the ring was bent...once corrected and returned to spec they fit as designed. That can happen to ANY rifle/bayonet made.

Two P1913 bayonets re-stamped for US service.

This one is in British P1907/1913 type scabbard with oval locket. I doubt either scabbard is original to these bayonets.

Same bayonet, different markings, different scabbards. Basically the same rifle except the caliber change and volley sights on some p-14's. A lot of the parts interchange.

sure glad the thread finally got to the reality that the p13 rifle became a p14 but the bayonet remained a p13 , until both became m17s and yes all fully interchangeable , both had the grooved scales save for possibly some early vickers p13s , this one is wearing p07 scales ,

That's where I was the first day...

But are you sure?

When I have tried fitting my P17 bayonet to my P14 rifle I will report back on the results. This bayonet was made from scratch as a P17 bayonet. If it fits my P14 rifle I will I will agree that the P14 & 17 bayonets and rifles are fully interchangeable. If, however, the P17 bayonet doesn't fit the P14 rifle and this is not due to any sort of damage/distortion etc I will be most interested to hear all the explanations from every-one who has insisted that they are fully interchangeable. I will not be seeing if the bayonet fits the rifle this evening as I have other things to do but at a convenient time for me I will do so.

I agree with Jim, the bayonets for the Rifle P14 and the US M1917 Rifle are the same, unless there is damage to the bayonet's muzzle ring. If it fits one than it will fit both.

We will find out when I try fitting the bayonet to the rifle.
