Looking through the loft for my Tasco custom shop (boxed with christmas tree ret and large sidewheel)

I came across a Leupold 6.5-20 x 40 that has been boosted by Premier Reticles (via Nick Jenkinson) to 14-35 (I think from memory) with 50 ft adaptor in butler creek as was de -riguer in those days. (no box)

What are these both these scopes worth please ?


TIA
