Hopefully, the M-71 qualifies for a 'Classic Single Barreled Sporting Rifle'...

I recently picked up a 71 Deluxe which has had the buttstock chopped maybe 1-1/2" and some awful black and white spacers added along with a 1" recoil pad. I assume my options would be a) find a take-off and hope the wood and finish match; b) have one made from scratch; c) send the stock off to someone like DES for an extension.

What would one expect to pay for each of these options?

Are there other options?

Thank you for your time,
