Webb Mini replica mower

Hi all,

I have a mini replica mower from webb, that i had as a child and is the same as the one in the following link

My mower is the same as this but is not in the same condition however my challenge is to see if it is a collectable or indeed has any significant value.

I found a note that there is one in the Victoria and Albert museum, however no picture but comments. 

Could anyone on te site help me with any information regarding this please, it would be very much appreciated .

Many thanks 

James
