I'm restoring a 20" bmx frame and would like to know maker, model and year so I can restore to original as possible. There are two numbers on the bottom of crank housing.

                     MBI-2325 
                     294558

is on top and

                     WIU253
                     P0153D

is on bottom.

Thank you for your help!

    Can you include images of the frame and anything that may stand out such as logos, decals, interesting lugs etc it will help greatly in identifying it if possible. Welcome to SE Bicycles! – Nate W Jan 20 '17 at 19:16

Google is your friend. Based on a report from the South Yorkshire Police , they received a report of a stolen BMX with "mbi-2325" as the "serial number" in 2010. Seems to be a mistake in that was a frame model and the serial number is one of the other values.

However this same police report lists it as

MIRRACO BLEND 2 BMX BIKE BROWN 09

which means little to me. More Google returns http://www.vitalbmx.com/product/feature/Mirraco-Blend-Two-Complete-Bike,2275
