Rare Antique WW1 German Bavarian Pickelhaube Leather Spiked Helmet

Description

Straight from the estate of a well-known military antique collector which includes over 30 helmets and pickelhaubes from pre-WW1 and WW2 era that will be listed on my page in the near future
(pictures available upon request)
.  None of these helmets have been professionally authenticated that I'm aware of and I am NOT an expert myself.  Anything mentioned herein is simply my uneducated opinion.  That said, all helmet sales are final and returns will not be accepted.  Please take that into consideration and please ask any and all questions you may have before bidding.
This particular helmet is in decent shape overall with no major signs of trauma or visible damage.  It appears to be structurally sound and straight but shows obvious signs of age.  The exterior leather is mostly still in great condition with no tears or holes but some crazing on the front/rear brims and the stitching on the rear brim is starting to come apart.  The leather chinstrap is still fully intact but is hard and cracking from age.  Metal parts are oxidized with some discoloration but nothing that couldn't be cleaned up.  One of the wheels is missing from the side.
The inner liner is degraded and very worn as seen in the last picture.  "J.B. Dott"? stamped on the inside of the front metal brim, although it's a very small stamp and hard to decipher exactly what it says.
As previously stated, I am NOT an expert on these helmets but I have done my best to detail this item and point out any noticeable
discrepancies that may concern you as a buyer.  If I missed any important details or you want me to check something in particular, please ask before bidding.
This does not appear to be a reproduction but its authenticity cannot be guaranteed.  Stand seen in pictures not included.
