Supplies of British tanks decreased by 1943. Matilda enjoyed popularity with the Russians for her strong frontal armor etc. and the American Sherman for its armor, reliability and comfort for the crew. At the same time, British tanks (Churchill) are visible in the photo on the streets of Kiev in the days of the liberation of the city in the autumn of 1943.there were 8 convoys in 1941 , 15 during the 42 sailing season
After the disaster of pQ17 in late June 42 , the convoys were stopped ,
much to Stalin ire , some convoys were send in mid September
but the sailing season was short no ships sailed in winter
the battle of Stalingrad was fought with Soviet resources ,
the number of 4697 tanks in 41 42 ( I suppose it include January 43 ) seems surprising
Britain supplied a little more than 5000 tanks for the whole war ,
during the whole of 41 , 1084 Mathildas were send but only 918 received
I'm digging for the Valentine numbers
are you sure you don't include the "universal carriers" tankette in the number

Matilda II in Soviet Service - Tanks Encyclopedia
"By the end of 1941, some 182 British tanks had been committed to combat operations, of which around 80 would be lost in action. By this time, there were only 46 Lend/Lease tanks still operational on the Western Front, this consisted of 38 Valentines and only eight Matildas. Many Matildas were pulled back from frontline service due to the Matilda’s shortcomings in harsh winter weather. "
Theу move along the center of Kiev which was completely destroyed by explosions of Russian land mines with radio detonators in September 1941 after the Germans entered the city. Prior to this, the city was absolutely not affected by the fighting.
It must be said that the Soviet political leaders and the NKVD made great efforts against praising the Western armament in the Red Army, so good words about British and American tanks can be heard only in the responses of Russian veterans recorded in recent years - when the syndrome of fear to tell the truth gradually passed
The whole phrase about the number of tanks under the Lend-Lease from that source looks like this -
In 1941-1942 The Red Army received 4,697 tanks on Lend-Lease, in 1943 - another 3026.

That is, the number of tanks in the Russian requests for lend-lease after 1942 was reduced on the whole. They preferred to receive instead of tanks scarce materials, machine tools and equipment that they could not produce.
And they did the tanks well themselves. At the same time, it is necessary to say about the main shortcomings of the most popular Russian tank T-34.
All models with a 76mm cannon that dominated before 1944 had a very poor visibility for its crew. The gearbox of this tank was disgusting. And I read that many tank drivers used only the second gear - on it they drove on the march and in battle. Switching the control levers of the tank for the driver was very hard. And for this the radio operator/machine gunner (радист-стрелок) of these T-34 models often helped the driver (Rus. - механик-водитель) pull arrows to the next gear lever as he sat near the driver . The intercom system of the crew was unreliable and noisy, so the commander often gave signals to the driver for driving the tank, kicking him on the back or on the shoulders. The driver-mechanic saw almost nothing during the battle, and he often had to drive with a half-open hatch in the frontal part of the tank with more risk to be wounded or killed.
A very large upper hatch on the T-34-76 opened with great difficulty, and often this required the efforts of two or three crew members. In a burning tank this often prevented the crew from quickly getting out. After several shots, the tank was filled with powder gases, and it was very hard to breathe in it.
When an Armor piercing shell (non-explosive) got into the tank even without penetrating the armor, lots of the fragments of the armor flew out from its inside part and damaging the crew. During a heavy rain inside the tank, a real flood often began.
There also were problems with radio stations. On many T-34s, they have not been installed for a long time. Thus, on June 1, 1941, the Red Army had 671 “linear” (линейные) T-34 tank (without a radio station in general) and 221 - “radio” (радийные) (with just a receiving radio station, less often with a receiving and transmitting one). The radio stations themselves were of poor quality for a long time. Due to problems with the evacuation of enterprises from August 1941 the production of tank radio stations in Russia was practically ceased until the middle of 1942.
By the middle of the war, the Russians began to release new and quite high-quality tank radio stations (РСИ-4 - 9Р ). The radio station was of English origin and for a long time it was produced using lend-lease components. This radio station was praised by Russian tankers.
