Marlin model 88 semi-automatic tube fed through the rear of the stock .22 rifle. These were only made from 1948 to 1956 and were Marlin's first tube fed semi automatic 22 rifle. The bore and rifling are in great condition. It does have the grooves on the top of the receiver to mount scope rings and put a scope on it. I redid the stock and it's all cleaned up ready for the range. $300 call or text 785-259-8140 or message me on here. Thanks
