I need an actual account name and the name of your bank because I need to physically go to the bank and pay the money into your account.
Given that you are quite a new member, and the gun you are selling doesn't appear to have been bought from this forum - and also that you say it is a prototype - I would like some sort of guarantee that I will get a working gun in return for my £175.
Hence my request for an address and telephone number.
Then, should I not receive a working gun, we can have a chat about it.
If you are not prepared to give me these details, no problem. I'll pass on the gun, and you can sell it to the next guy in the queue.
