The original Anschultz company started making the Flobert action single shot .22LR in the early 1900s. In 1925 Anschutz became JGA (which stands for Julius Gottfried Anschutz). The company changed their name several times and each variation marked some sort of new partnership or business arrangement until we get the J.G. Anschutz GmbH & co of today.
In 1925, JGA was the 2nd variation of the Anschutz's name and the single shot .22LR Flobert design was the rage in Europe. Winchester had a similar single shot .22 in the United States at that time. All of the Winchester's I have come across are in pretty rough shape but still command a premium. I think it is a combination of cheap materials used, so most of the rifles did not survive the test of time and the rifles that are in very good condition are hidden in people's safes to be past down to the next generation.
In Europe on the other hand, these rifles were everywhere. They were sold as farm guns, pest control guns and training rifles. They are very good rifles and a lot of the other manufactures such as FN made them but by far Anschultz or rather JGA made the most accurate ones. If you could get over the fact that it is a single shot, they really keep up to today's rifles. They are light and simple and even though you have to #### the striker (I am probily using the wrong terminology again. Lol) on each shot, you could still get off rounds pretty quickly. Very fun to use at the club or in the woods. The only real problem is the lower breach extractor. The extractor works great but they are often lost during cleaning and are now impossible to replace. The extractor is just sandwiched between the bolt and the receiver and is not being held by anything else. Take the bolt off and it will fall out and if it does so in the woods it will be lost forever. The wood is a lower to middle grade walnut which got better through out the years. Anschultz and other manufacture alike used a v notch rear sight along with a bladed bead front sight.
These are still quite a few of these Anschultz single shot for sale. In the US, they sell for between $200-300 in good condition. Shooter's Choice has a later varient (maybe from the 1940/50s?) on their web site for $195. I just picked a 1925 model up about a month ago at the local gun shop for $40 in good condition. I am shooting 3" groups at 35metres at the club, which is very respectable considering, the age of the rifle, the sights and my old eyes. If you find one in good condition, don't hesitate. Best $40 I've ever spent and the rifle is quickly becoming one of the house hold's favourate which is no small feet when it is competing with 5 full safes.
