Carlo, that H-22 looks to be in great shape and to have the OSSC with it in the same condition is a rare find. Congrats on your score!
I use to have an H-22 many years ago and have recently been hankering for a "true semi acoustic" bass to noodle around the house with. The H-22's I found online seemed overly expensive to me for what they were. My alternative was an original Swedish Hagstrom Concord, another bass that I've also owned in the past and really enjoyed.
Luckily I found a 1967 Hagstrom Concord for sale about 2.5 hours away from me by car. I made an offer subject to a hands on inspection which was accepted. It's condition was very good and the price was quite reasonable, so I bought it. I own a copy of Hagstrom`s production records with all serial numbers of every instrument they made, so it was easy for me to trace it which was how I was able to see that it was made in 67. Here`s a photo.
