Not a field jacket but an M1951 parka made in June 1953. A nice find for what you paid for it. The liner is all wrong but if you want an original size medium wool frieze M1951 parka liner I've got a one listed in the "for sale" section or, at least, I think the ad is still there. Finding original parts may be a challenge unless you find a ratty old parka you can strip parts off of Greg
Horse riding is a very challenging experience. Especially, if you’ve never ridden a horse before. The first challenge for you is to saddle up your horse. Initially, it is really hard and thrilling to maintain your balance. To control your horse, you have to master special motions, which are unusual for your body. You should sit straight in the saddle and press knees and legs firmly against the sides of the horse. Try to move with the rhythm of its movement. Finally, you will be very pleased and at the same time excited when you will manage with all challenges.
