Verification photos to prove that the seller actually has the rifle today to sell is a good idea e.g. a photo of the rifle with a specific object or something like a newspaper or TV news screen showing today’s date. The asking price is way below its asking price last year, less than half. Try to check the seller’s reputation too as it might be a scam using copied photos. That has happened at least once that I know of for a No.4 Mk.I (T). I would only expect such a price from someone who bought the rifle about 1970 for $100 and is content with that asking price, or someone who is desperate for cash flow. The rifle is real I believe but is the seller? The old story “If it is too good to be true, it probably is not.” A face to face transaction would be ideal. Hopefully the rifle is not a stolen one.
