SELEV Patent Leather Hairnet Cycling Helmet (Eroica) - NOS - Size M/L

Description

Background story:  Back in the 90's I had a small bike shop (that specialized in road cycling) and over the years I have collected a large collection of bike stuff.  I need to start down-sizing and I'll be selling off the majority of my collection.  I will start doing rounds of auctions by listing similar items (posters/books/collectables...bars/stems/bar tape...frames/forks...tires/tubes/rim strips...wheels/rims/hubs/cassettes...helmets/sunglasses...clothing/shoes...saddle/seatposts...etc).  Please check my other auctions for other similar items.  I will combine shipping the best I can (for multiple purchases).  Feel free to contact me if there is something you're looking for.  I might not be able to list all of the things I have.
For sale is a NOS (new old stock) SELEV patent leather hairnet-style cycling helmet, not in the bag but never worn.  This one is mainly white with red/white pads.  I believe I bought these hairnets in 1990, so I'd put them circa 1988 to 1990.  I had a Cinelli one that I wore the most (available in a separate auction).  I have several more SELEV (and a Cinelli) leather hairnets in separate auctions.  I also have some other colors (and sizes) available in my other auctions.  I also have some of those old foam helmets worn in the mid 90's in my other auctions.  Please take a look at my other auctions to check them out.
I would put it at a Size Medium/Large.  My head measures 57.5cm and this helmet fits me tightly.  I'd put it down as a 56cm(ish), but I can wear it at a 57.5cm circumference.  It was a stretch to find a cotton cap to fit over these helmets, so I'd cut the tops of the caps and wear them under.  My top of head to below the chin measurement (for chin strap) is 69cm.
Please make sure you check your head size before ordering this helmet.  I won't take returns, so measure carefully.  Also, it should go without saying that this is in no way a crash worthy helmet!  These were worn essentially before hard shell helmets were widely available.
Please ask questions of you have any.
