As for the L-52 project, here is its three-view drawing attached. As well as the basic specifications:

Span: 12.5 m
Length: 12 m
Empty weight: 2214 kg
T/O weight: 5670 kg
Max. speed: 920 kph
Landing speed: 162 kph
Range: 1000 km
Engine: RR Nene I
Armament : two 30mm automatic cannon MK108 or two 20mm MG151 plus built-in launcher for 55mm folding fin rockets. 210mm rockets or two 250kg bombs under wings (or fuselage)

A training version (with RR Derwent) and night fighter two-seat variant were being contemplated either.

Best regards,
Piotr

Hi Hesham !
The LK-1 was actually built. However, this Letov design was from Yugoslavia and not from Czecho-Slovakia.
Some info:
4-seat sport
one 160hp JW-6-III (Walter Minor 6-III) piston engine
max. speed 119 mph, cruise 93 mph, icr 492ft/minute, ceiling 14,000ft, range 310 miles
wingspan 37.073ft; length 24.604ft; height 7.217ft
DETAILS: This high wing light 4-seater was an original design of Mr. Anton Kuhelj and initially planned as 2-seater, but during the design stage it was decided to make the LK-1 a 4-seater. The type was built by Letov Works in Ljublana and the first of 3 aircraft was flown on 5 January 1955. At a later stage a taller vertical tail was fitted. The LK-1s served with Yugoslav aero-clubs for many years.
PS: Other sources claim the aircraft were built by Aero Technicki Avod and also referred to as ATZ-55 (?)
