Hi Eleanor

Absolutely, the smaller B3770 that you’re referring to is the same one used in this video and the video at the link here: http://amtechdiy.com/amtech_questions/i-put-staples-staple-gun/

Paul has answered the additioanl part of your question in this video, so I hope this is of use. If you have any more questions, fire away here: www.amtechdiy.com/ask
