Could you mean Siberian Gold rather than Russian?

No it’s definitely a Russian Quince. I saw one growing in an Hotel garden ( I was staying in) in the Cotswolds. I did try to grow one from the seed of a fallen fruit ( as they were so amazing) but had no luck.
Sorry I have tried to add a photo but not sure how to do it

Hi, try looking for Cydonia oblonga 'aromatnaya', Derek.

Yes Derek I do believe you are right.
Thanks for the correct name
Do you know if they grow well in this country

Hi, well they are hardy down to 5f [-15c], they like a fertile, moist but well drained soil, in full sun, if it gets any colder, regularly where you are, then you can grow them against a wall, fan trained, Derek.
