Hello! I just joined yesterday. So I’ve been collecting since I was 18 and really have been getting into the hobby for a while now. I collect mostly radios/phones and rations. That is my niche.I’m about to upgrade to a much better display in about a week. I just wanted to show off my collection and passion as a young collector. 

My 2 cents worth.  Defiitely not Greek, almost all of those Ive seen had a very dark black parkerized finish and the stock were saturated with cosmoline.  Nor do I believe it was rebuilt as most of the parts appear to have the original finish intact,  again the chances are they would have been replaced or refinished with Parkerizing.  I'm not even sure the stock is a replacement, it was common for soldiers to "bone" the surface to make it look better and in the process the inspector marks were lost.   Congrats on a nice rifle.   

I'll give it a shot at answering this since no one else has yet. There's SO much to consider when evaluating the price of rifle such as yours, but here's just some things to think about.  Your rifle may be in slightly less condition than fair, I'm just not sure.  If you really want to know you might be better off getting an opinion on a firearms forum.  That said,  An authentic Kentucky Tiger Maple Rifle (American Longrifle) in fair condition, converted from flintlock to percussion, generally has a market value ranging from $800 to $1,500. The percussion conversion is very common for 19th-century models and does not inherently hurt the value, however, the exact value of your antique piece depends on several critical factors like: Maker & Provenance: Rifles signed by known gunsmiths (e.g., Leman, Golcher, or regional Pennsylvania/Virginia makers) fetch a premium.  Also visible stamps are taken into consideration.   Wood Quality & Artistry: Highly figured tiger maple (curly maple) with ornate brass patchboxes, silver inlays, or carved stocks will drive the price toward the higher end.   Caliber:  Can make a difference in valuation. "Fair" condition generally implies a dark bore, heavy patina, and some handling wear, but all major original components should be intact without major amateur wood repairs.  

As I understand the marking of helmets indicates a student or class ID number? Something like that was mentioned in the previous linked thread. Pics for reference, the 1st vintage pic is from the linked thread, the 2nd recent image was just pulled off net

Greetings to all. Growing up, my Dad had in the house an old trap door with a detachable bayonet with scabbard. We always used to play with it. My older Brother got it. Today I have acquired this model 1884 Springfield.  I have never owned one but am looking forward to getting it in and  shooting it. Seller gave the following description...   For sale is a Springfield Model 1884 Trapdoor rifle assembled in January of 1891. The rifle has lost the bulk of its finish, but instead has a nice patina and grey color on the metal. The trapdoor has also lost its case coloring. The stock shows surface scuffs but no cracks or breaks. The bore is bright with strong rifling, but there are occasional spots of surface pitting within the last 6 inches of the muzzle. The rifle has the ramrod bayonet assembly at the muzzle.      Knowing nothing really about these, can anyone please give me some feedback on what they think of it by the photos? And some tips on suitable ammunition for it tips etc?   Thank you. Cheers!  

Here is another Robbins WW1 era wing on eBay, this one has the complete “Sterling” stamp in the blob location.        https://ebay.io/m/78E4oe

You are probably right as I check my photo reference library on ovals for the 221st Airborne Medical Company and found this bullion example which has a purple border, silver (white) inner border and what looks like a medium blue center.   Sometimes it is difficult to tell the true color of the embroidered oval from a bullion example but I think this is a match.  This of course means that besides the wrong era the original oval does not match the DUIs on this uniform. 

Check this find-a-grave entry: this is likely your officer. https://www.findagrave.com/memorial/18512823/john-holloway-skirving    

We'd previously received some of Private Ruttle's World War I artifacts; Matthew called to say they located his campaign hat so our Curator picked it up last night. The box was in pretty bad shape and the family pondered throwing it away...but, although not a perfect restoration, it didn't come out too bad. This hat has an unusually high peak at 7 inches....also the slits for the chin strap string.  There's low grommets under the hat band as well.  The sweatband has his initials "RDR" written on it.     Mark sends

These aren’t my specialty and I might be wrong but from what I see they appear to be a copied version of a post WWI EGA. There is a whole thread on EGA’s as well as their copies on this website that you might want to look at. Hopefully someone else with more experience weighs in on them. Cheers.
