I am fixing up a beat up Parker for a field trial gun. Well, mostly my shooting student Joe Wood has done all the fixing. But anyway it has several cracks in the stock. It is already as ugly as a man's ass so pretty doesn't matter. I am looking for directions on how to glue these cracks up or otherwise repair the stock. I am going to shoot 1-1/8 oz 1200 fps low pressure loads in it. No hot loads.
Here are the pictures Joe took for me:

This is the same angle with the loose piece removed:


The right of the picture is where the end of the top tang is inletted:

Same area, different angle:

Thanks in advance.
Best,
Mike
