Welcome to the forum. Pictures are nice!
You can put an S&K scope base on it, with out needing to drill it; search forums here for prior S&K posts.
Also folks like Sarco sell just the front end for your stock, they are stupid expensive, and a real pain to graft back to your stock.
Its much better to find a replacement stock, new or old (about the same cost) unless you get crazy for an exact match to what you have then it will cost you.
Stocks are for sale on flea-bay, here in the forums, Sarco and Numrich; and even at CMPicon; just be careful of new stocks, fit and finish vary. (I understand the CMP stuff is good).
Good Luck
