Many thanks MadMike.
A guy on here was quick to offer help!
I'm not on here often, but I always get fantastic results.
just for your reference here, in case anyone would like to do the same with theirs, I have a 'WE airsoft silencer set' it was priced at £24.99
now it isn't an exact match to the ones actually used, but its close enough for me. since buying it however, I noticed another airsoft suppressor that may have been a better match, but I have since forgotten the make and model.
