I did receive the ledger page. Posted it a while back but here it is. Mine is 16706. Looks to have been made with 16705 as it is exactly the same. Seems to me they got an order and made two rifles to the specs and sold the second one. You can see it looks to have occurred with the rifles after. Would like to have the 303 serial 16703. Apologies I have not measured the magazine follower as yet.
