These are very cute - here is a pretty set of three Larry the Lamb Models.
They are marked on the bottom with both the Plichta and Midwinter marks - as photographed.
The base stamp reads:
Plichta Made in England H H & G LTD Registered No. 791377 / "Larry The Lamb" Midwinter Porcelain Burslem England
It was originally designed by Plichta in the late 1930s / 40s by Nancy Great-Rex.
All three lambs are in perfect condition with no damages or restorations - there is general crazing obvious on close up inspection but this is commensurate with age - and often found on these pieces.
Nice to find a graduated set: they measure as follows: Height: 8 ¼ inches; 7 ½ inches and 5 ¾ inches.
