MAUSER G29/40

Question
Getting older and considering selling this, does it have any value?
Mauser K98 G29/40, Code 660, Dated 1940, Serial number 46xx.
Very smooth action and trigger.
Very nice condition for its age.  Lots of READABLE proof marks. No visible import marks. Number matching is not 100%, but very,very close, all the way from the butt plate to the front band. While I am certainly not an expert, I offer the following non-expert opinion. No visible rust or pitting above or below wood.  Some parts (front band, Butt plate, and areas of trigger guard) show some patina.  Bluing on most of rifle 75-80 % or better. The Rifle has nice a laminated, K98 stock which sadly I believe I sanded and refinished quite a few years ago.  No visible markings, numbers, proofs on outside of stock or hand guard, but 46xx inside stock in barrel channel.  Stock has normal handling dents and dings, but nothing deep. One small visible (approx. 3 inch) crack from Butt plate forward in mid portion of Butt on right side. It is not wide or deep, and does not run through to the other side. No repair required.  I believe the hand guard is a replacement,   (No number or proofs)
Rifle has been stored in dry So. California and Arizona, since purchased.
I purchased this rifle in the early 1960抯 while in college, with the intent of converting it to a. sporter configuration. Because the 8mm barrel BORE was in very poor condition, in the late 60抯, I obtained a replacement barrel from Sarco.  The .308 (Israeli ?) stepped Mauser K98 barrel was installed, head spaced and test fired by a local (California) gunsmith.   Rifle has not been fired since the new barrel was installed. The original barrel is history. The front and rear sights remain with the rifle, but were not reattached by the gunsmith at my request.  The sights could be reattached. The rear sight barrel ring slipped on to the barrel, but not attached.  All the numbers on the rear sight match, except the barrel ring, as detailed below   

What parts carry either the number 46xx or the xx number in addition to receiver, working from the Butt Plate to the barrel crown
1.   Butt plate
2.   Stock, in barrel channel
3.   Bolt stop has xx number. The ejector appears to be proofed only.
4.   All bolt parts, (bolt body, extractor, firing pin, shroud, safety, cocking sleeve) except the extractor collar is and as stated below the retaining pin plunger which was not removed to inspect for number
5.   Follower
6.   All rear sight parts, except sight barrel ring as stated below
7.   Front band
8.   Rear band
9.   Sear (bright and clean, but in the white)
10.   Two large trigger guard screws
11.   Stock nose piece with Bayonet fitting

What parts do not have a number or do not match receiver?  (Because I have no idea what parts normally were numbered and which were not)  By proper proof mark below, I mean what appears to be an eagle icon over a number or letters in addition to numbers (as close to 損roper?as a proof mark laymen can manage).

1.   No number visible on trigger guard, which is a very nice stamped part. It does have a proper proof mark
2.   Barrel of course
3.   Handguard
4.   No numbers or proofs on springs or pins
5.   No number on small capture screws, but numbers match on two large guard screws.
6.   Number on floor plate is 3814 with proper proof marks
7.   No number visible on stock cross bolt parts, but bolt face has a proper proof mark
8.   No number visible on front sight parts, but there is a proper proof mark
9.   No number visible on rear sight barrel ring, but proper proof marks, and an 揝?on the bottom
10.   No number visible on butt plate screws
11.   No visible number on the trigger, but proper proof.  I did not remove trigger from sear to inspect the upper portion of the trigger, but this rifle does not appear to have been disassembled and if the number usually appears in the upper portion, the odds are high the number is there..
12.   No number visible on Bolt stop screw
13.   No number or proofs visible on Band spring
14.   No visible number on bolt shroud plunger, but as stated above, I did not remove it for inspection
15.   No visible number or proofs on cleaning rod
16.   No visible number on the EJECTOR in the bolt stop, but it is proofed


Answer
All Mausers have value, of course from a collector standpoint, being rebarrelled to .308 doesn't help. As far as shootability and being a good gun as is, or to be further sporterized it does have value.  Being non-import and mainly matching helps also. It's probably a $150.-200. gun right now, if you switched it back to 8mm, it would probably be worth more collector-wise, as even the Wehrmacht armorers would have changed out barrels if the rifling was worn. I do have an 8mm K-98 barrel kicking around the shop in decent shape. To me, it being chambered in a caliber I can buy at Walmart is a plus, not a minus. Thanks.
