I found the Enfield test data and what a wealth of information !!... Main difference between my rifle and the test rifle is that mine has 7 groove rifling and the test rifle has 5.. the test barrel is 3 foot, 3 inches long while my sample is significantly less than 3 feet. The test rifle also likely had a socket bayonet and barrel bands and my sample is rigged to accept a saber bayonet and barrel is pinned. (reason is that the test rifle weighed in at under 10 pounds with bayonet)
Similarities are that both my rifle and test rifle are in .530 caliber and rear sight is consistent with mention in the documents
I am not sure if that leads us to what this rifle represents? Is it a factory sample, a special order or a fanciful experiment. The bayonet feature confuses the issue and the rear sight is military.. What this may be is an experimental design that would lead to the 2 band enfield with saber bayonet.. 1856 and 1858
That makes some sense.. and that may be where this story goes. Just no data to back that up that I have seen.
After pouring over images, test reports from Enfield and taking in all the great input offered by some experts in the field, I have come to somewhat of a conclusion on this piece. I am the Student here and bow to the wisdom of those who have so much more insight but here are my thoughts.
Conclusions (2 possibilities ??)
I believe this rifle is a sample made at Wilkinson as a possible companion piece to the submitted rifle that found its way to Enfield in 1852 for testing. The fact that it has a saber bayonet mount along with a P51 rear sight and is in the same unique caliber (.53 inch ) as the submitted rifle, leads me in that direction.
It merges features of the Brunswick P37 (second model).. saber bayonet, pinned barrel, hook breech, muzzle profile is snubbed, centered notch on the bayonet lug …and the P51 Rifle musket insofar as sight and lock.. The caliber is unique and the rifling is a throwback to the Baker ( 7 groove)
I believe this rifle was made as a sample but never submitted.
Another possibility is that internally, Wilkinson did its own experimentation and independently showed this rifle to British Ordnance or intended to prior to the British Army adopting the 3 groove .577 P53… Once the P53 was adopted, this rifle became irrelevant.
The bayonet attachment has the notch in the middle, similar to the 2nd Model Brunswick but instead of having a squarish or angled form, the attachment on my rifle is round and dowel or rod shaped. Location is same as on the Brunswick.
It is not a production rifle.. It is a specially made weapon with a totally unique bayonet attachment and metal ramrod.
