A few things I haven't been using for a while.
1. 3 x Centra High-End Foresight Inserts
In 3.1mm/1.4mm, 3.6mm/1.4mm, 3.7mm/1.4 diameter/ring thickness.
Only the 3.7mm was used. Kept my favourite two sizes.
New price £20 but selling individual inserts for £10 each + Royal Mail 2nd-class signed-for £3.90.
Or £30 for all three, no extra for Royal Mail 2nd-class signed-for.
2. Gehmann 503-09
Fits any modern Gehmann iris. Magnifies to 1.5x & provides -4.5/+4.5 optical correction. Comes with 577 thread adapter.
Didn't work for me 'cos I'm very long-sighted, but if you are short-sighted it could do the trick!
New price £75/80 euros, selling for £45 + Royal Mail 2nd-class signed-for £3.90
3. Gehmann 579 Cylindrical lens system. With a 579-III 'diaphram' adapter
Goes for around £110-117 new. Fixes astigmatism, but I found that pushing my cheek into the cheek-piece just that little harder, also fixes my astigmatism!
I don't believe it is ISSF-compliant, so best for club shooting. Worked for me late in the evening indoors, but I shoot outside mostly now. Selling for £60 plus Royal Mail 2nd-class signed-for £3.90
If purchased with the 503-09, then £105 for the both of them, but free Royal Mail 2nd-class signed-for. The additional pictures are of the 503-09 and 579 assembled with a 510 iris (not-for-sale) and the 503-09 and 579 assembled without an iris.
Everything - 1,2 & 3 as a job-lot - again, without the 510 iris - £135 and again I will pay for Royal Mail 2nd-class signed-for postage. Note all of the items are out-of-warranty.
I'm attending the Scottish Shoot for the weekend, and Bisley, again for the weekend, and Sywell in-between (both days). If you'd rather take a look at the items (remaining) before buying, I'll bring them along. Off-site though (meaning not on the premises), so not to annoy the vendors who attend those meetings.
Otherwise PM for Paypal details.
