Mac, it would be good if you could get some photos up. Maybe that stock is salvageable in shooter context. Bedding material curing internal ills, if any. Some of the modern glues & paints, I'd suppose to cure structural/aesthetic ills. In all this, Mac not to insult you with pablum dialogue. Just don't know your knowledge/skill levels & attacking the described situation in basic terms!
BSA, I don't know much about the most recent decades of aftermarket 'plastic stocks'! Are there any OK types reasonably priced, available for the prewar vintage Model 70 rifles? Perhaps a source there? Otherwise eBay perhaps!
Best!
John
