The Model 1902 is a single shot, bolt action rifle. It is a low cost "boys" rifle and it is interesting that someone put an expensive Maxim silencer on it. The Model 1902 was quite popular, with some 640,000 made between 1902 and 1931. It was a successor to the Model 1900 and similar to that gun. It is also similar to the slightly fancier Model 1904 which was made at the same time.
There is collector interest, and value on a Model 1902 could be as high as $500 for one in new condition. An average would be around $150, with a bit more for those chambered for .22 Extra Long and for early guns with only the Short and Long marking.
If you are not in the U.S. I have no idea how much the presence of the silencer will affect the value.
If you are in the U.S. and the silencer is registered, a $200 tax would have to be paid on its transfer; if it is not registered, then as noted above, its possession is illegal.
