1968

Your fuze has a modern spring and striker, the fuze bouchon is a M10 series fuze, most likely a later model since it doesn't have the early features. So maybe A2/A3. It's near impossible to know for sure as the det cap is gone and no sealant is still there to help ID it. The ring is most likely a early replica or off a novelty, most I have seen are solid single rings like that, especially with the pin being longer than an original M10 pin. 

Here is the bottom

Can anyone Identify what model MK2 grenade fuze this is by looking at the pictures? Also can anyone tell me why my pin is a solid ring and not a spiral key chain thing. I can confirm the pin, spoon, and fuze, and grenade were all original together from factory. Can anyone grade my grenade for its type out of all you have seen? It looks shiny because there was oil put on to prevent oxidation. It comes off. I really don't want it to oxidize, thinking about a think coat of renaissance wax? Has anyone used that stuff? I stuck skewer through it to prove it's inerted clean empty  Grenade MK2 Pineapple manufactured Watertown Massachusetts at The Arsenal during WW2.    Back story for those who have not seen my posts.  I'm the guy who's grandfather worked at the Watertown Massachusetts Arsenal during WW2 manufacturing weapons and development and inherent a fuze and ordnance collection. My uncle at easter said he put the cut fuze on because it looked cool and showed me where the original inert fuze was that belonged to it. I really wish the paint on the fuze and yellow band was absolutely mint but I'm a profectonist so it kills me to see even the smallest flaws

Great stuff, thanks for this information . 

Would you be willing to sell this piece 😁

@gap I have added updated information to the AVFS thread that @KevinBeyer linked earlier, if you want to read more on the AVFS     The badge you posted could possibly be an encampment badge. The membership badge has cutouts inside the circle, which this one does not. The AVFS did not adopt a badge until late 1902 or early 1903. So, if this is an Encampment Badge, it would be one of only a few years (through the process of elimination)  1905, 1907, 1908 or 1911.    Alternately and also another highly likely possibility is that it is a pocket watch fob. The attachment point at the top makes me think this. 

Cliff has a Blackinton Aeronaut wing marked with VHB.  I don't know how long after 1921 they would have kept producing Aeronaut wings.

The badges shown here are a Type 1 (Eagle top) and Type 2 (AVFS Top) and Type 3   On September 29th, 1899 in Columbus, OH, a Veterans organization was formed that would become one of several founding societies of the VFW. This organization called itself the American Veterans of Foreign Service.    The Third National Convention of the AVFS met at Washington Courthouse, OH, and was in session October 11 and 12, 1902. At this Convention the National President was authorized to offer a prize for the best badge design. I have not been able to find a written report or outcome of this, but the physical examples show the result.    At some point the top bar changed to the AVFS bar, shown here are two sets of letter head form 1909 and 1910 showing this badge.    In September, 1903, three separate Veterans organizations that were formed in Pennsylvania met in Altoona, PA and amalgomated to become the American Veterans of the Philippine and China Wars. During the ensuing year, at the suggestion of the Executive Committee, this name was was changed to American Veterans of Foreign Service. They were unaware of the pre-existing OH group by the same name. This newly merged society did not have a membership badge of their own.    In 1904 the two groups found out about each other and started talks to merge into one national society. In 1905 these two groups met in Altoona, PA and completed the merger. The newly merged society adopted the badge of the Ohio group.   At the annual convention held in Buffalo, NY, August 23rd, 1911, a new badge was proposed and adopted. This would be the Type 3. This badge is seen here on the cover of the souvenir book from the 1912 Encampment.   The AVFS would complete its final merger in Denver, CO, in 1913 with the Army of the Philippines and become the Veterans of Foreign Wars.   Bobby Welch National Historian Veterans of Foreign Wars    

Thank you for the help.  I love it.  If it could only talk!
