As per the other thread, having looked at the auction photos and seen the "B5506" serial number I would say George Gibbs probably did the mounts as that is almost certainly their stock number, as per a few other Scotch Deer Stalkers that have turned up with similar numbers applied.

Some records are here , and some are in the hands of this company. Some were also lost in the bombing of Bristol in WWII IIRC.

Here is an early type Zielvier fitted up by Gibbs for a mount system like this:

Here is another SDS with slightly later(?) Gibbs bases.

Thank you for the pictures and information. If having a B serial no. on the trigger guard means it was modified by Gibbs then mine is a Gibbs as well. His name appears nowhere on the gun.

Your pictures of the scope indicate that it cannot fit my base. Thanks. p.

That's not the scope I referred to in my PM, but one seen perhaps on eBay years ago.

Might be worth contacting the firm linked above in the UK to see if they can pull up original sales records on the rifle. That would presumably settle the question of whether that is a Gibbs base or something added later.

I don't remember any of the Gibbs .280s that have surfaced being marked other than scope tubes and with those B prefix numbers.
