Whistle swap?

Hi guys! I would love to try an Mk low whistle, just to see if i would like to purchase one in the future. I am making a proposal to someone here that would like to swap whistles with me for a week. I have a Hammy Hamilton Low D. So, if there is someone with a Mk Low whistle who would like to try out a Hamilton, please let me know. This is not a permanent trade, it is only swapping for a week or so.
