You are looking at a limited edition Mercedes Motorsport release of the 1:43 Mercedes W13 showcar from the 2022 Belgian Grand Prix - made by Spark Models (Mercedes Product Code: B66960657).

The 2022 Belgian Grand Prix saw both Sir Lewis Hamilton and George Russell sport a slightly altered livery for their Mercedes W13 car, showing classic versions of their race numbers, as well as AMG celebrating 55 years in Motorsport, in deference to the 1971 24 Hours of Spa Mercedes 300 SEL 6.8 AMG "Red Pig" car, celebrating 55 years of the AMG performance arm of Mercedes. 

The F1 W13 E Performance showcar sported a full rendition of what was supposed to be the team's livery for that race, but was ultimately unused as an actual race livery due to potential weight issues, and with a triple header underway from F1's summer break, this would not have worked for the team to simply remove the red from the front half of the car.  This car featured the full front of the W13 with "Red Pig" colours, with a special numbering (#63 for Russell and #44 for Hamilton) and AMG stickers to celebrate the occasion.  On the track (with the slight livery update), George Russell guided his Mercedes to a 4th place finish in the race, but Sir Lewis Hamilton retired on the first lap after a collision with the Alpine of Fernando Alonso.  

The model features the Mercedes F1 W13 E Performance showcar as it appeared at the 2022 Belgian Grand Prix weekend on display, albeit with the race car's zero sidepod design instead of the pre-season sidepods.  It is a Mercedes Motorsport Edition that is limited to just 500 pieces worldwide, featuring the Red Pig livery and the numbers of Hamilton and Russell on each side of the car.  It is also the first Mercedes F1 Edition to feature the manufacturer Spark Models, instead of their preferred brand Minichamps. 

The model and box are both in new condition, and comes with an outer plastic sleeve (opened only for photos). 

Thanks for looking :)
